Bartosz Bosacki (born 20 December 1975) is a Polish former professional footballer who played as a centre-back.

On 22 May 2006, Paweł Janas called up Bosacki for the 2006 World Cup as a replacement for Damian Gorawski, after the latter failed medical tests upon being diagnosed with severe asthma.

Bosacki scored both goals in Poland's group-stage 2–1 win against Costa Rica on 20 June 2006,[2] which were the only goals scored by the Poland national team during the games.

He has been capped 20 times for Poland and scored two goals.
