Alexander Gerndt (born 14 July 1986) is a Swedish footballer who plays as a striker for Lugano in the Swiss Super League.
Born and raised in Visby, on the island of Gotland, Gerndt started to play for the island's top club Visby IF Gute during his youth system. As Gute's second best goal-scorer, he drew attention from Swedish top league clubs such as Örebro SK and AIK. On 3 November 2006, he signed a three-year contract with AIK. In 2007, he only made five appearances in the league, all without scoring. Struggling to make it into the starting 11, he was loaned out to the second tier club Sirius prior to the 2008 season. In Sirius, he made 14 appearances, scoring six goals.
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. His start in Gefle was not a success at all; he did not score any goals for the club during 2008. In the season of 2009, Gerndt played 26 out of 30 league games (14 as a starter), scoring 3 goals.
