马尼波戈（英语：Manipogo）是加拿大马尼托巴省马尼托巴湖的水怪的名称。关于水怪的最早目击可以追溯到19世纪初，大约1908年起，这种蛇形水怪便不断被目击。当地的土着居民也有水怪的传说。这种生物在1957年被命名为马尼波戈，以响应不列颠哥伦比亚省发现的欧戈波戈。在温尼伯戈西斯湖也有被命名为温尼波戈的水怪，并且很有可能是同一种，因为这个湖与马尼托巴湖是相连的。许多专家认为水怪正确的名称应该是被当地居民认可的“温尼伯戈”（Winnipego）。

水怪被认为有12英尺至50英尺长。它被描述为有“一个土棕色的露出水面可见肉峰（humps）的长躯干和一个羊头。”

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 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 believe the correct name is Winnipego, as confirmed by local residents.
