Marko Baša (Serbian Cyrillic: Марко Баша, pronounced [mâːrko bǎːʃa]; born 29 December 1982) is a Montenegrin retired professional footballer who played as a centre back.

On 23 June 2011, Baša returned to France after three years in Russia with Lokomotiv Moscow, signing a contract with 2010–11 Ligue 1 champions Lille.

He was part of the Serbia and Montenegro 2004 Olympic football team that exited in the first round, finishing fourth in Group C behind gold-medal winners Argentina, Australia and Tunisia.

He received a call-up from Serbia national team by head coach Javier Clemente for the away friendly against Czech Republic on 16 August 2006 (first match since Montenegro left the state union)[3] but did not show up - apparently because of an injury.

[4] Then, in late May he apparently did not respond to Montenegrin football officials' attempts to get in touch with him and as a result he wasn't included in the team that went to Japan to play in Kirin Cup.
