The arrests in the capital Ankara came a day before celebrations across the country for the 94th anniversary of Republic Day.
Turkish authorities issued warrants for 55 suspected foreign IS members, believing some were planning an attack on Republic Day, Anadolu reported without giving further details.
Turkey has been hit by several bloody attacks blamed on IS militants over the past two years, including a New Year attack this year on an elite Istanbul nightclub during which 39 people were killed by an IS gunman.
There has been a lull in attacks since, but tensions remain high and Turkish police launch raids almost daily against suspected IS cells across the country.
