Seepark, Lakeside recreational park in Donaustadt, Vienna, Austria

Seepark Aspern is a 48,200 m² park in the Seestadt Aspern development area of Donaustadt, Vienna's 22nd district. It is bordered to the north by the Asperner See, a groundwater lake about 47,000 m² in size and up to 10 metres deep, and to the south by the Janis-Joplin-Promenade. The park is divided into four areas with lake-related themes, containing playgrounds such as the Seespielplatz and the Seepferdchenbucht.

The site was formerly part of Aspern Airport, which operated from 1912 to 1977 as Austria's largest airport. After closure, the area was converted into a traffic training facility before eventually becoming the foundation for this park.

The park's four themed sections carry lake-related names, among them the Seespielplatz playground and the Seepferdchenbucht. The adjacent lake is officially called Landschaftsteich Seestadt Aspern, and swimming is tolerated at two pebble beaches on its southern shore.

The southern shore of the lake stretches over 750 metres, with two pebble beaches where wild swimming is permitted. Dogs are banned throughout the park except in a fenced 2,942 m² dog zone at the eastern end, at the corner of Janis-Joplin-Promenade and Sonnenallee, which has its own lake access for dogs. Two running routes start in the park and lead east via Seestadtstraße, over the Asperner Terrassen or through the Gedenkwald, before returning to the park.

The Rollinsel skate spot lies directly beneath the U2 Seestadt station, which spans this part of the park. The park also bans dogs except in a fenced 2,942 m² dog zone at the corner of Janis-Joplin-Promenade and Sonnenallee, which has its own lake access for dogs.
