Mart Müürisepp (born October 28, 1991) is an Estonian stage, film, and television actor.

In 2008, while still attending classes in the 10th grade at the Jakob Westholm Gymnasium, Müürisepp was approached to appear in the starring role of Tom in the Hannu Salonen directed crime-drama feature film Vasha, about a naïve sixteen-year-old schoolboy who finds himself to be an unwitting accomplice in a deadly game of vengeance after befriending Artur (played by Mehmet Kurtuluş), a Chechen man who is eager to avenge the murder of his family. After filming was completed, Müürisepp returned to Jakob Westholm Gymnasium to finish his secondary education as well as studying acting and puppetry from 2009 until 2011 at the Estonian Puppet and Youth Theatre (NUKU) in Tallinn.
