Interlake was a provincial electoral division in the Canadian province of Manitoba.

Communities in the riding include Arborg, Riverton, Ashern, Fraserwood.

Prior to the 2019 Manitoba general election, Interlake was abolished and its area was redistributed to the new riding of Interlake-Gimli.

Interlake had been represented continuously by members of the New Democratic Party since its creation.

The plan was unsuccessful, but caused a major provincial scandal when its details were revealed to the public in 1998-99.
