'Grimoald IV' (assassinated 817), called 'Falco', was the
Lombard Prince of Benevento from 806 until his death. He was a ''thesaurarius'' or ''stolesayz''/''stoleseyz'' before becoming prince on the death of
Grimoald III, over Grimoald's own son, Ilderic, another ''stoleseyz''.

In 812, he was forced to pay 25,000 ''
solidi'' in tribute to
Charlemagne. In 814, he pledged an annual tribute of 7,000 ''solidi'' to
Louis the Pious. These promises, however, were never kept and his successor,
Sico, made the same empty guarantees. The Beneventans were independent in practice and by the end of the ninth century would not even recognise Frankish overlordship. Grimoald was assassinated in 817 by a complot of nobles vying for his throne.
