Petre Mitu (born 22 March 1977 in Bucharest) is a Romanian former rugby union fullback. A one time captain of the national team, Mitu played as both a fullback and scrum half during his career. He was also their goalkicker, helping Romania qualify for the 1999 Rugby World Cup with 80 points during qualifying.
An injury in 2001 saw him lose the goalkicking duties to Ionuț Tofan and soon after he announced his retirement despite being just 25 years of age. He finished his international career with 34 caps for Romania and a total of 288 points (the highest total for a scrum half, as of October 2008).
