The 1958–59 season was the 54th season of competitive football in Turkey.
The Milli Lig was introduced in 1959. At the time, there were three cities who had professional leagues: Ankara, Istanbul, and İzmir. The first league was made up of sixteen clubs, with eight from Istanbul, and four each from Ankara and İzmir. To gain entry, qualification tournaments were held in 1958 to decide who would participate in the league. League play did not start until the second half of the season, causing the season to be played in group format and a shorter game schedule.
The first final was held between Fenerbahçe S.K. and Galatasaray S.K. The match was a two legged knockout. Galatasaray won the first match 1-0, while Fenerbahçe won the second 4-0 and secured their first title by 4-1 aggregate.
This year was also earmarked by the first competition of a Turkish club in the European Cup. Fenerbahçe won the first match of the preliminary round 4-3 on aggregate over Csepel SC. Their second preliminary match came against OGC Nice. Fenerbahçe had tied after two legs, but lost the playoff leg 1-5.
