St. Nicolai is a church and Lutheran parish in Lüneburg, Lower Saxony, Germany.

The building was erected on the site of a former chapel which the town council had initiated while other churches were built by religious orders.

[1] It features a prominent nave with a "star" rib vault which is unique in today Northern Germany.

[3] Twenty years later, a steeple was built, but it was not completed due to financing problems, and proved unstable.

In 1843, an association for the rescue of the church was (Verein zur Rettung der Kirche), achieving first a stabilisation of the nave, then the building of a new steeple.

[1] Behind the choir (Chorumgang), parts of a former high altar from the dissolved monastery Heiligenthal are shown.

It features reliefs carved in Lüneburg c. 1425 and paintings from c. 1450 with four scenes from the life of the saints Laurentius and Andreas.
