Sergiu Florin Buș (born 2 November 1992) is a Romanian professional footballer who plays as a forward for Liga I club Hermannstadt.
Born in Cluj-Napoca, Buș began his senior career at CFR Cluj, where he totalled three goals from 19 Liga I appearances while playing sporadically between 2009 and 2014.

Buș was re-signed by Gaz Metan Mediaș for the 2019–20 Liga I season, and managed to score ten goals from 30 games in the competition, which inspired a move to FCSB.
He was called up for the first time to the seniors for the UEFA Nations League group matches against Northern Ireland and Austria in September 2020, but did not make his debut.
