Rostokino District (Russian: райо́н Росто́кино) is an administrative district (raion), one of the seventeen in North-Eastern Administrative Okrug of the federal city of Moscow, Russia. It is located on both banks of the Yauza River and borders with Yaroslavsky District in the northeast, Sviblovo District in the northwest, and Ostankinsky District in the south.
The district takes its name from the village that stood in this area before being subsumed by Moscow, whose name in Old East Slavic literally means river split.
As a municipal division, it is incorporated as Rostokino Municipal Okrug.
