The Split Channel (Croatian: Splitska vrata, meaning "Split Gates" or the "Gates of Split"), named after the nearby city of Split, is a narrow passage between the islands of Brač and Šolta in Croatia's Dalmatia region. Situated on the eastern coast of the Adriatic Sea, it is the quickest seaway to the regional capital, Split. In the channel lies Mrduja, an islet notable for being the turning point of the local Mrduja Regata, a yearly sailboat competition.
On the Brač side lies deep Milna bay and the village of Milna. On the Šolta side of the channel, there are no villages in the immediate vicinity.
