Taastrup (or Tåstrup) (Danish pronunciation: [ˈtsʰɒstʁɔp]) is a Danish railway town and suburb of Copenhagen – 18 km west of Copenhagen's city centre. The town forms a twin urban area with neighbouring suburb Høje Taastrup, Taastrup rising since 1859 and Høje Taastrup rising west of the town, since the 1970s. The town/suburb development has engulfed the villages of Taastrup Valby, Høje Taastrup, Kragehave and Klovtofte, although Høje Taastrup still has a preserved village character around Høje Taastrup Church. The town is the administrative seat of Høje-Taastrup Municipality, Region Hovedstaden; the seat placed in Taastrup first and since moving to Høje- Taastrup in the beginning of the 1980s. In 2023 a new town hall was opened on 14 February.

The town is growing closer to the town of Hedehusene, both towns developing towards each other, and both situated in the municipality. The population on 1 January 2025 was 38,178 (excluding Hedehusene).

Taastrup took its name from its rise on the lands north of the village of Taastrup Valby. Taastrup Valby means "Valby by (Høje) Taastrup", named "Taastrup Valby" to avoid confusion with other locations like Valby.

The town is situated approximately halfway between Copenhagen and Roskilde, in proximity to the Copenhagen suburb/new town Albertslund, the town of Hedehusene and the villages of Ishøj Landsby, Sengeløse and Vridsløsemagle.
