Şehzadebaşı is a quarter (Turkish: semt) of the Fatih district in the European part of Istanbul. Although its exact boundaries cannot be drawn as it is a quarter, administratively it covers part of the mahalle of Kemalpaşa and Kalenderhane. It is a busy centre due to its proximity to the quarter of Saraçhane, Vezneciler and Unkapanı.

It hosts the Şehzade Mosque, one of the first works of Mimar Sinan.

The quarter is served by the M2 metro line, which came into service in March 2014, with a station at Vezneciler.
