St. Nicholas' Church, Catholic church in Opfingen district, Freiburg im Breisgau, Germany.

St. Nicholas' Church is a Roman Catholic filial church built from 1984 to 1986 to plans by Freiburg architect Michel Geis, using regional Breisgau materials: sandstone, plastered masonry and wood. The east-oriented building has a deep stepped saddle roof and a massive hexagonal tower on the east side, also under a tiled saddle roof. Its symmetrical plan is dominated by triangular forms, and the pale plastered walls with tall dormers face the road at the village entrance.

St. Nicholas' Church was built from 1984 to 1986 to plans by the Freiburg architect Michel Geis, on Freiburger Straße at the entrance to Opfingen. The parish chose the patronage to recall the former St. Nicholas chapel in the St. Nikolaus hamlet of Opfingen. The single bell cast in 1986 by the Karlsruhe bell foundry was joined in 2019 by three bells from Bachert, forming the Salve Regina motif.

The church's patron, Saint Nicholas, recalls the former St. Nikolaus chapel in the St. Nikolaus hamlet of Opfingen. The oak entrance portal, carved by Freiburg sculptor H. P. Wernet, shows the blessing saint; Wernet also made the red sandstone celebration altar, ambo and baptismal font inside.

The church stands on Freiburger Straße at the entrance to Opfingen, on a grass strip beside the road. The entrance portal is carved from oak and shows Saint Nicholas blessing. The interior is lit by natural light; the organ is on the gallery at the rear.

The second-largest bell was cast by the Karlsruhe bell and art foundry and hung in the tower from 1986, long before the church had a full peal. In 2019 the Bachert foundry added three bells, turning the single bell into a four-voice peal on the Salve Regina motif.
