Repetitor is a Serbian alternative rock band from Belgrade. The band was formed in 2005 by guitarist and vocalist Boris Vlastelica and drummer Milena Milutinović, who were soon joined by bass guitarist and vocalist Ana-Marija Cupin.

The band's early performances gained them public attention, and their debut album, Sve što vidim je prvi put, was met with positive reactions by both the audience and the critics, making them one of the most prominent bands of the so-called New Serbian Scene. The band was formed in Belgrade on Autumn of 2005 by Milena Milutinović (drums) and Boris Vlastelica (guitar, vocals), who had been playing together as a duo for a while, joined by Ana-Marija Cupin (bass, vocals). Without much skills at their own instruments, Repetitor started performing live after only a few months of rehearsing, during early 2006 at the Belgrade club Blue Moon. In January 2007, the band was pronounced by the webzine Popboks critics as the third greatest debut act of the year 2006. After the album release, the band started a live promotion of the album, performing at the Jelen Pivo Live festival.

In January 2010, the band released another promotional video, for the track "Ogledalo" ("The Mirror"). In July 9 of the same year, the band performed at the Novi Sad EXIT festival main stage. In October 2016, the band released their latest studio album entitled Gde ćeš (Where Are You Going) through Slovenian independent record label Moonlee Records. The album was followed by concerts in former Yugoslav countries, Slovakia, Czech Republic, Netherlands and Austria. On June 30, 2017, they had a performance in Belgrade District Prison. The video for the song "Ako te ikad" ("If You Ever") was recorded on the performance. The band announced the release of a documentary film about the performance.
