The St.-Aegidien-Kirche or Aegidienkirche is a church building in the north German city of Lübeck, dedicated to saint Giles. It is the smallest and westernmost church in the city centre. It is first mentioned as dedicated to St Giles in 1227 - this is unusual for a north German and may link it to an earlier 1172-1182 wooden church built under bishop Henry I, formerly the abbot of the abbey dedicated to the same saint in Braunschweig. The church's coat of arms includes a "T", short for "Tilgenkark", the Low German form of the church's name, and "St Tilgen" or "St. Illigen", the Low German forms of the saint's name.
