Alexander Clas Robin Gerndt (born 14 July 1986) is a Swedish professional footballer who plays as a striker.

As Gute's second best goal-scorer, he drew attention from Swedish top league clubs such as Örebro SK and AIK.

Although it was thought that he would stay the entire season on loan at Sirius, he signed for Gefle in the top flight division during the summer transfer window of 2008.

[8] Gerndt continued to score goals and was a major reason that Helsingborg could battle against their biggest rivals Malmö for the title into the last round of the league.

[9] Helsingborgs IF, aware there was a big risk that Alexander Gerndt would leave the club, started to look for replacements already in March 2011.

[16] Alexander Gerndt's first game with FC Utrecht did not come in the team's premiere game of the season on 6 August 2011; the Swedish Discipline Committee suspended Alexander Gerndt between 5–7 August as a result of an incident on 23 July when he punched Malmö player Miljan Mutavdžić in the head, and the suspension was carried over to FC Utrecht as the Dutch Football Association (DFA) was notified by the Swedish Football Association (SFA) of the suspension.

Alexander Gerndt had a great chance to score the game-winning goal in the second half, but the shot hit the inside post.

[20] On 31 January 2013, the last day of the 2012–13 transfer window, it was confirmed that Gerndt had joined Swiss Super League club Young Boys.

This handed him an indefinite ban from the Sweden national team, as decided by the Swedish Football Association (SvFF).
