Johan Helge Dahlin (born 8 September 1986) is a Swedish professional footballer who plays as a goalkeeper for Malmö FF.

With both Al-Habsi and Marques gone after the season, and having made a good impression during the winter months, Dahlin became manager Henning Berg's preferred choice in goal, ahead of newcomer Eddie Gustafsson.

After the summer, the roles were reversed and Dahlin received little playing time, only making one more appearance when he came on a substitute for an injured Gustafsson.

Therefore, in a bid to receive playing time at a high level, Dahlin agreed to a loan deal with Swedish side Trelleborgs FF.

These problems continued during the 2010 season but as Dahlin himself and club doctors worked hard to minimize the pain he was able to play all games except one and a half.

On 23 December 2013, Malmö FF confirmed the transfer of Johan Dahlin to the Turkish Süper Lig club Gençlerbirliği under contract until 2017.
