A massive fur seal that's spent Boxing Day wandering a Tasmanian suburb's streets and sitting on a car has been tranquillised.

Dubbed "Mr Lou-Seal" by Tasmania Police, the public were warned to stay away from the giant sea mammal in Newstead, Launceston, to avoid agitating it.

Police and Parks and Wildlife officers spent much of Monday morning trying to capture the seal so it could be moved.

It was tranquillised before 11am and Parks and Wildlife officers will then move Lou-Seal, Tasmania Police say.

The seal has already made its mark in Newstead, climbing on to a car to leave large dents and a broken windscreen in its wake.
