In many team
sports, a 'goalkeeper' (termed 'goaltender,' 'netminder', 'goalie', or 'keeper' in some sports) is a designated player that is charged with directly preventing the opposite team from scoring by defending the
goal. Such positions exist in
hurling,
association football,
Gaelic football,
International Rules Football,
handball,
field hockey,
netball,
water polo,
lacrosse,
floorball and a number of other sports. In
ice hockey he or she is referred to most commonly as a
goaltender or "netminder".
Overview
Usually special rules apply to the goalkeeper that do not apply to the other players. These rules are often instituted to protect the goalkeeper, being an obvious target for dangerous or even violent actions. In addition, in certain sports like ice hockey, goalkeepers are required to wear special equipment like heavy pads and a face mask to protect their bodies from impact from the play object (e.g. a puck). In association football goalkeepers wear gloves that are protective to the hand because the fingers can be bent back.
Examples
Football

Youth-football goalkeeper
In
association football, each team's goalkeeper defends his team's goal and has special privileges within the game. The goalkeeper's main job is to stop any penetration of the ball into the goal.
The goalkeeper is the only player who may use his or her hands to play the ball (although only within the
penalty area). The goalkeeper is required to wear a jersey with a color very unlike his/her or the other teams jersey color to avoid confusion for the referee. Goalkeepers often wear gloves to aid in catching the ball.
As the goalkeeper is usually the team's only player who can see the entire field, they often act as an organizer of the team when it is defending
Field hockey
In
field hockey, the goalkeeper generally wears extensive protective equipment including helmet, face and neck guards, chest and leg padding, gloves, lower leg guards (known as pads) and shoe covers (known as kickers). Only the helmet is compulsory, as is a shirt of a different colour from any of the other players. He or she is also equipped with a stick; either one specified for goalies or one used for normal play. The goalkeeper is allowed to use any part of their body to deflect the ball, although they can't obstruct its play (for example by lying on top of it), and they can only do so within the goal circle (or "D"), and they are not permitted to pass their team's 23m line, with the exception of goalkeepers who take penalty strokes.
Gaelic football
In
Gaelic football, the goalies main task is to prevent a goal from being scored against their side by directly defending their goal. A goal occurs when the ball passes through the goal; the attacking team is awarded 3 points. The goalie is the only player who may handle the ball on the ground, and only inside the small rectangle.
Hurling
In
hurling, the goalkeeper's main task is to prevent a goal from being scored against their side by directly defending their goal. A goal occurs when the ball passes through the goal; the attacking team is awarded 3 points. The goalkeeper has no special rules pertaining to him, although he still wears a different colour
jersey.
Ice hockey
International rules football
In
International rules football, a hybrid game between
Australian rules football (which does not have a goalkeeper) and
Gaelic football, the goalkeeper's main task is to prevent a goal from being scored. A goal occurs when the ball comes off any part of an attacking player and passes through the goal; the attacking team is awarded 6 points.
Field and Box Lacrosse
In men's
field lacrosse, once a goalkeeper makes a save and has control of the ball in his crosse (stick), he may only remain in possession of the ball inside the protective crease for four seconds (the length may depend on the level of play). Before the four seconds is up, the goalkeeper must either pass the ball or leave the crease. After leaving, he may not re-enter the crease with possession of the ball.
While inside the crease (nine feet in diameter), offensive players may not make contact with the goalie or his stick. Doing so is declared "interference with the goalie" and is penalized by a free clear to the half field line. (There is a significant difference between NCAA/MLL rules and international rules regarding a pass while the goalkeeper is inside the crease: under NCAA/MLL rules, contact with a goalie's stick while in the act of passing -- even after the ball is released -- is prohibited and considered interference. Under international rules, protection ends when possession ends. Therefore, contact with a goalie's stick after the ball is released, is legal.) In addition, a goalie is allowed to make contact with the ball with his hand, although he is not allowed to control it or pick it up.
In
women's lacrosse, once a goalkeeper makes a save and has control of the ball in her crosse, she may remain in possession of the ball inside the crease for ten seconds. The interference rule is similar to men's lacrosse; unlike in the men's game, a woman goalkeeper is allowed to control or even pick up the ball in her hand.
In both men's and women's lacrosse, goalkeepers are required to wear a helmet and 4-point chinstrap, a throat protector, gloves, and a chest protector. Use of a protective cup is, for obvious reasons, required in the men's game; thigh pads and shinguards are also being required for women goalkeepers as of 2007. Many goalkeepers elect to wear optional protective equipment, including elbow and shoulder pads, thigh pads and shin guards, and long sweat pants.
Interestingly, in international competition, American and Canadian goalkeepers seem to only wear a minimum of protective equipment, while European goalkeepers "bundle up". Asian and Australian goalkeepers tend to split the difference. Humorously, Canadian Chris Sanderson, starting goalie for the Canadian team in the 1998 and 2002 World Games, plays with a "bullseye" target painted onto his chest protector.
In
Box Lacrosse, a goaltender is typically more heavily armored than a field lacrosse goaltender and plays with a net that is four feet tall and four feet wide, except in the
National Lacrosse League and
Major Series Lacrosse where the nets are the same height but four and a half feet wide. The crease rules are relatively the same, except that the punishments for different infractions include a change of possession, resetting of the time-clock, or a possible two minute penalty depending on the infraction. Box lacrosse goaltenders are known for their massive upper body gear, large shin guards known as "irons", and
ice hockey-style helmets. Also, below the professional level, box lacrosse goaltenders are often seen using traditional wooden sticks.
The box lacrosse goaltender is allowed to play in any area of the playing surface and is not confined to any zone. It is not uncommon to see a box lacrosse goaltender run up and join the play in the offensive zone on a
slow whistle. Goaltenders in box lacrosse are known to score goals for their team, usually in
powerplay or
slow whistle situations. Also, due to the unique lack of
offsides rules in box lacrosse, it is not unheard of to see a goaltender lead his team in scoring on game sheets through mulitple
assists, usually through long passes to teammates that are attempting to
breakaway on unsuspecting defenders. Box lacrosse goaltenders are also encouraged to be aggressive
stick checkers around the ball and ferocious
cross-checkers when needed (cross-checking is legal in lacrosse). If a goaltender leaves the crease with posession of the ball, opponents are allowed to cross-check the goaltender as long as there is no attempt to injure.
Netball
A
netball goalkeeper is one of two players who are permitted to remain within their defensive shooting third, and is restricted to the defensive third of the court.
Water polo

Goalkeepers in
water polo are granted three special privileges when inside the four metre area:
★ The ability to touch the ball with two hands.
★ The ability to touch the floor of the pool.
★ The ability to strike the ball with a clenched fist.
However, they have one limitation that field players do not have: they may not cross the half-distance line.
Rule change in 2006:
The four and seven meter lines were merged to a five meter line. A goalie may now under revised rules:
★ Use two hands until the 5m line
★ Use the bottom until the 5m line
★ Go beyond the 5m line according to the field rules (one hand, no bottom) and not pass the half line.
★ Strike the ball with a clenched fist (not recommended)
New cap rules:
★ A goalie cap must now be in quarters alternating red/dark for home and red/white for away
★ The goalie must be number 1, 1a, or 1b
★ For females: a red swim cap must be worn under the goalie cap, a team's dark swim cap is no longer acceptable as it is hard to distinguish a goalie from field players if official cap is off.
These revisions are according to the NFHS 2006-2007 swimming/diving and water polo rulebook. USWP and NCAA rules may vary slightly.
