NGC 3191 (also known as NGC 3192) is a barred spiral galaxy in the constellation Ursa Major.

It was discovered on 5 February 1788 by William Herschel.

It is located at a distance of about 400 million light years from Earth, which, given its apparent dimensions, means that NGC 3191 is about 115,000 light years across.

The galaxy has been distorted and interacts with a companion about 0.5 arcminutes to the west, a galaxy identified as KUG 1015+467.

An extremely blue tidal bridge lies between them.
