St. James’s Church, Heiligenstadt (Heiligenstädter Kirche St. Jakob) is one of two Roman Catholic churches in the parish of Heiligenstadt in the 19th district of Vienna, Döbling. It stands at the Pfarrplatz and is dedicated to James, son of Zebedee (Saint James). The church is sometimes wrongly called St. Jacob's. The confusion arises because German, like many other languages, uses the same word for both James and Jacob.
The church takes the form of a simple Romanesque structure. Its modern-day appearance dates back to the 12th century. The church consists of a single nave with a raised and slightly offset choir. The left-hand side of the church has three round arched windows; the right-hand side only two.
