Boniface (1 December 1244–7 June 1263) was Count of Savoy from 1253 to 1263, succeeding his father Amadeus IV.

[1] Boniface's other uncles, Peter and Philip, disputed this, seeking to divide the county's many properties, but Thomas took it to arbitration per the family treaty of 1234 which had been negotiated by his brother William and won out.

Peter and Philip were, however, granted compensation in return, receiving more properties within the county.

Under her regency, Philip and Peter continued their previous work of expanding the control and influence over the County of Savoy.

[5] On 7 July 1263 in Turin, Boniface was mortally wounded in battle[citation needed] and died aged 18, to be succeeded by his uncle Peter.
