Marius Delport (born 6 March 1985) is a South African former professional rugby union player.

He represented South Africa's under-19 and under-21 national sides, captaining the latter to victory in the 2005 World Championships.

He was often restricted to the bench, including for the 2009 Super 14 final win over the Chiefs, prompting a move to the Lions in 2010 seeking more opportunities.

[3][4] Delport left South African rugby in 2013 and had three seasons playing in Europe, linking up first with French Pro D2 side US Dax.

He left at the end of his second season after the team came close to relegation, signing a one-year contract with Italian club Viadana, coached by his former Bulls teammate Casper Steyn.
