Świętego Macieja Square, Wrocław, Historic square in the northern part of Wrocław, Poland.

Świętego Macieja Square covers about 1.8 hectares in Nadodrze, north of Wrocław's centre. Its northern part is nearly rectangular, while the southern corners are cut off, and a semicircular street links Bolesława Chrobrego and Trzebnicka streets. The central green has a fountain and a public toilet, and the surrounding buildings are 19th-century tenements of three or four storeys in classicist and Neo-Renaissance styles, with turrets and bay windows at the corners.

The area was a marshy, undeveloped tract called Matthiasfeld (Pole Maciejowe) between the city estates and the Norbertine monastery lands. In 1253 the Ołbin manor there was given by Dukes Henry III and Władysław and their mother Anna to the St. Matthias hospital. In the 14th century the site lay in an enclave of the Knights of the Cross with the Red Star. The square itself was laid out in 1873 to designs by O. Bauer and G. von Drabizius, and building around it continued until 1885.

The square takes its name from Saint Matthias, to whom the medieval St. Matthias Hospital was dedicated. In 2013 a magnolia was planted on the central green to commemorate Anna German, the singer who lived at nearby Trzebnicka Street 5. The square has also been known as Lignicki, Legnicki and Fryderyka Engelsa.

The square is easily reached by public transport and sits at a junction of local bus routes serving the neighborhood. Nearby shops and cafés make it a natural stopping point when moving through the district.

The central green was laid out with a fountain in the 1873 design by O. Bauer and G. von Drabizius, modelled on an English garden-square. In 2013 a magnolia was planted there in memory of the actress Anna German, who lived at nearby Trzebnicka Street 5. A public toilet also stands on the green.
