Gut Niederhofen, Manor estate in Wellinghofen district, Dortmund, Germany.

Gut Niederhofen is a former knight's seat in the Wellinghofen district of Dortmund. Of the estate, only the gatehouse with a baroque hood and two wing buildings from 1748 survive. Behind the historic buildings today is a child and youth welfare facility with residential groups.

Gut Niederhofen was first mentioned in 1242 and was built by the Lords of Niederhofen as a knight's seat. In 1479 Cord, brother of Johann von der Lage von der Dorneburg, was enfeoffed with the house and farm at Niederhofen in the Amt Hörde and parish of Wellinghofen by the Count of Limburg. In 1535 Heinrich von Haus acquired the seat through marriage to Margarethe von der Lage and was enfeoffed with it in 1548.

The name Niederhofen appears in variants such as Nierhofen and Nierhoven in old records, and the estate lay in the parish of Wellinghofen, about 5 km from Dortmund. In 1535 Heinrich von Haus acquired the knight's seat by marriage to Margarethe von der Lage and was enfeoffed with it by the Count of Limburg in 1548. Today the grounds behind the gatehouse house residential groups of a child and youth welfare facility.

The gatehouse and the two 1748 wings stand behind the historic building fabric and belong to a child and youth welfare facility with residential groups, so they are viewed from outside only. The estate is the trailhead of the Sauerland Mountain Association's A1 and A2 hiking routes through the Niederhofer Wald.

The gatehouse's baroque hood is the only surviving part of the estate's older building stock; the two wings beside it date from 1748. The complex is listed as a Baudenkmal in Dortmund's monument register, and the hiking trails A1 and A2 of the Sauerländischer Gebirgsverein start right at the gate.
