Kniepertor, Medieval city gate in Stralsund, Germany.

The Kniepertor is a brick gate tower at the end of Knieperstraße facing Olof-Palme-Platz. It is 11.50 metres wide, 8.60 metres deep and 20.80 metres high, with a windowless unplastered base, two upper storeys with tall windows and a shallow pointed roof. The passage is a masonry pointed arch about seven metres wide.

The gate appears in written records from 1293 and was one of ten city gates protecting Stralsund's medieval defenses. It survived sieges and wars, remaining to this day as evidence of the city's medieval fortifications.

The gate is named after a citizen family of the 13th century, not a merchant dynasty; the Knieperstraße leading to it carries the same name. Until the 1960s the Stralsund tram ran through the passage, and since the late 1990s it has been reserved for pedestrians and cyclists. Iron holders for the barrier chains that once protected the open gateway can still be seen on the gate.

The gate is located on Knieperstraße and easily accessible on foot from the city's Old Market district. The surrounding area is easy to navigate and provides access to historic neighborhoods and local shops.

A memorial plaque on the city-facing side honors Friedrich Gustav von Petersson. It marks his service alongside Ferdinand von Schill during the liberation wars of the early 19th century.
