Paul Willemse (born 13 November 1992) is a French-South African professional rugby union player, who plays as a lock for Top 14 club Montpellier and the France national team.

[10] For the start of the 2013 season, Willemse made the short move across the Jukskei River to join Pretoria-based side Blue Bulls.

[15] Still eligible to play at Under-21 level, he made four appearances for the Blue Bulls U21 side during the 2013 Under-21 Provincial Championship, but he firmly established himself in the first team, starting ten matches during the 2013 Currie Cup Premier Division.

[19] In June 2014, it was announced that Willemse would join French Top 14 side Grenoble after the 2014 Currie Cup Premier Division competition.
