Victor Matfield (born 11 May 1977 in Pietersburg (now in Limpopo Province), South Africa) is a South African rugby union player. He has played for, and captained the Springbok rugby team as well as the Blue Bulls in the Currie Cup and the Bulls franchise in Super Rugby. He is generally considered one of the best locks in the world and has had a long successful partnership with Springbok and Blue Bulls teammate Bakkies Botha.

Besides almost always winning his own line-out ball, Matfield is known for his exceptional skill at disrupting opposition line-outs – this skill was a cornerstone of their 2007 World Cup success, where he was crowned IRB (International Rugby Board) player of the Rugby World Cup – and his speed around the field led former Australian coach Eddie Jones to comment that he should be an Olympic sprinter instead. He also possesses good upper body strength, with the ability to bench press 155 kg. In 2008 he became the first international captain to beat the All Blacks in New Zealand since Martin Johnson in 2003.
