Andreaskirche, Gothic Revival church in Steglitz-Zehlendorf, Germany.

Andreaskirche is a red-brick Neo-Gothic church on Lindenstraße in Wannsee, built 1896 to a design by Otto Stahn. It has a nave with a slightly recessed apse, a short transept and a square bell tower beside the north main entrance. A triangular gable with round-arched blind arcades sits above the facade's arched frieze, and a medallion of the Lamb of God hangs over the stepped-gable portal.

Wilhelm Conrad, founder of the Alsen villa colony, donated a church in 1889 because the old church at Stölpchensee was too far for residents. Johannes Otzen planned a larger building, but only his 1895 porch was built. Otto Stahn took over in 1896 with a new north-south design, and the church was consecrated on 15 August 1896. It was called Neue Kirche until 1965, when it was renamed after the Apostle Andrew.

The church has been named after the Apostle Andrew since 1965; before that it was simply the Neue Kirche. In the porch stands a bust of Wilhelm Conrad, made by Karl Pracht in 1895, honouring the banker who funded the church for his Alsen villa colony. A 16th-century oil painting after the circle of Tintoretto, showing Jesus and the Canaanite woman, hangs on the east wall.

The church stands at Lindenstraße 2 in Wannsee, a short walk from the S-Bahn station Wannsee. The main entrance is on the north side, beside the square bell tower; the porch by Johannes Otzen faces east. The gallery over the left transept can only be reached from outside.

The tower's three bronze bells were cast in 1896 by Gustav Adolph Jauck of Leipzig and still hang in the paired sound arcades beneath the octagonal spire. Above the main portal, a medallion of the Lamb of God decorates the stepped gable.
