SS Kuru was a steam ship which sank on 7 September 1929 in the lake Näsijärvi, in Tampere, Finland.

It led to the loss of 136 lives, according to the passenger counts and the officers; most sources frequently list the death toll as 138.

The capsizing was mostly due to an overly-high centre of gravity; in 1927, a third deck level had been added without expert help or inspecting the balance of the ship.

The wreck was raised in the same year and repaired; the ship had suffered only minor damage.

During the First World War, the ship served as a part of the Imperial Russian Navy's Satakunta Flotilla.
