St. Jacobuskirche, Cultural heritage church in Hambach an der Weinstraße, Germany.

St. Jacobuskirche is a church building in Hambach, a district of Neustadt an der Weinstraße, and displays typical features of German church architecture. The structure shapes the townscape with its stone construction and characteristic architectural details.

A wooden church stood on this site from the 9th century; in 1221 Bishop Konrad III of Scharfenberg of Speyer had it replaced in stone as a fortified Gothic church. Its choir tower was built in 1274 and carries wall paintings dated 1350. Between 1747 and 1750 the tower was raised, and in 1750–1751 Johann Georg and Johann Leonhard Stahl built the late-Baroque hall nave around it.

The church is dedicated to the Apostle James the Great, whose pilgrim attributes — staff, bread bag and scallop shell used as a drinking cup — appear in the altarpiece by Bruchsal court painter Johann Lothar Schweickart. The painting was lost for almost 40 years and was reinstalled in 2021 after eighteen months of restoration by Eva Lincul of Neustadt.

St. Jakobus stands at Freiheitsstraße 3 in Oberhambach, north of the Hambach district, on a spur of the Heidelberg; the Deutsche Weinstraße runs east of it. The churchyard holds a 1731 crucifixion group by J. J. Weber junior of Herxheim and gravestones from the 15th, 18th and 19th centuries. Vineyards of the Pfalz wine region begin immediately south of the church.

The high altar's central panel, painted by Bruchsal court painter Johann Lothar Schweickart, shows James the Elder as a pilgrim with staff, bread bag and a scallop shell used as a drinking cup. It was lost for almost 40 years and was reinstalled in 2021 after eighteen months of restoration by Eva Lincul of Neustadt.
