St.-Aegidius-Kirche, Catholic church in Seckenheim district, Mannheim, Germany.

St. Aegidius Church is a neo-baroque hall church built 1904–1906 to plans by Ludwig Maier, standing by the Neckar in Seckenheim. It is 35 m long, 14 m wide and 11 m high, with three naves, a transept and a recessed rectangular choir. The square tower at the southwest corner keeps its 18th-century lower section, raised and capped with a Welsche Haube; red sandstone articulates the facade, and a niche above the main entrance holds the Immaculata.

A church existed here by 823, when Emperor Louis the Pious gave it to Lorsch Abbey; it is one of the oldest churches on the right bank of the old Diocese of Worms. The medieval building was replaced around 1470, then by a Baroque church built 1737–1738 to plans by Sigismund Zeller. That church was demolished in 1904 and the present one, designed by Ludwig Maier, was consecrated on 27 May 1906. American artillery set it alight on 28 March 1945; Anton Ohnmacht led the rebuild, finished in 1951.

The parish belonged to the Seelsorgeeinheit Mannheim-Südost, now Mannheim St. Martin, formed in 2002 with St. Bonifatius, St. Andreas and St. Bruder Klaus. Behind the choir stands a red sandstone Nepomuk statue, moved here from a bridge on Schwabenstraße; the damaged 18th-century original was replaced by a copy around 1950.

The church is accessible from the street and situated within the residential area of Seckenheim. Visitors should keep in mind that regular services take place, and the interior is primarily available for worshippers during these times.

The tower's lower section survives from the 1737–1738 Baroque church by Sigismund Zeller; it was raised during Ludwig Maier's 1904–1906 rebuild and keeps its Welsche Haube (curved dome). Behind the choir stands a red sandstone Nepomuk statue from the 18th century, moved here from a bridge on Schwabenstraße and replaced by a copy around 1950.
