Manipogo is the name given to the lake monster reported to live in Lake Manitoba, Manitoba, Canada. Sightings of this serpent-like sea monster have been going on since roughly 1908. The creature was dubbed Manipogo in 1957, the name echoing British Columbia's Ogopogo. There is also a Lake Winnipegosis sea monster called Winnepogo, thought possibly to be the same creature as the lakes are connected. Some^[who?] have speculated that the monster sightings may be attributed to sightings of an unusually large lake sturgeon, or a relict population of prehistoric plesiosaurs. Although many experts^[who?] believe the correct name is Winnipego, as confirmed by local residents,^{[clarification needed]}

The monster is thought to be anywhere from 12 feet to 50 feet long. It is described as being "A long muddy-brown body with humps that show above the water, and a sheep-like head."

There is a provincial park on the west shore of Lake Manitoba named Manipogo Provincial Park.

St Laurent, a community on the south east shores of Lake Manitoba, holds a Manipogo festival the first week of March every year.
