Høje-Taastrup is a municipality (Danish, kommune) in Region Hovedstaden on the island of Zealand (Sjælland) in eastern Denmark. The municipality covers an area of 78 km², and has a total population of 45,948. Its mayor is Michael Ziegler, a member of the Conservative People's Party (Det Konservative Folkeparti) political party.
The main town and the site of its municipal council is the town of Høje Taastrup (without hyphenization). Other towns in the municipality include Taastrup, Hedehusene, Fløng, Sengeløse, Vridsløsemagle and Reerslev.
Neighboring municipalities are Albertslund and Vallensbæk to the east, Ledøje-Smørum and Gundsø to the north, Roskilde to the west, and Greve and Ishøj to the south. The Holbæk Motorway and the West Forest (Vestskoven) help define the municipality's eastern perimeter.
The Holbæk Motorway bisects the municipality east-to-west, and is a major roadway connecting Copenhagen through Roskilde to Holbæk; it extends all the way to the tip of Sjællands Odde, a peninsula sticking out into the Kattegat where a ferry connects to Denmark's mainland (the Jutland peninsula) at the town of Ebeltoft. Additionally Motorring 4 splits off from the Holbæk Motorway at the municipality's eastern border leading to the various motorways servicing the northern parts of Zealand. The municipality's good position in the traffic network has led to the development of Høje-Taastrup Transportation Center, which includes Carlsberg Brewery's huge bottle depot.
The West Forest is located where the three municipalities of Høje-Taastrup, Albertslund, and Ledøje-Smørum border on one another. It is part of a system of green areas surrounding the Copenhagen metropolitan area. It offers an extensive system of hiking and bike trails through grass and marsh areas. It connects to other parts of the greenway system, allowing one to seamlessly make a tour around the metropolitan area.
Historic milestone on Roskildevej. Erected by King Frederik V (1746-1766).Another throughway in this municipality is historic Roskilde Way (Roskildevej), which runs from Copenhagen to Roskilde. The first major road connecting these two cities was built in 1642 by King Christian IV. It was called The King's Road (Kongevejen), and was replaced in the 1700s by the current roadway. At Hedehusene, one of the towns in the municipality, the road changes name to Copenhagen Way (Københansvej), i.e. the road leading from Roskilde to Copenhagen. The Holbæk Motorway runs into, and has replaced part of the old Roskilde Way.
Road signs indicating that one is leaving the Copenhagen metropolitan area are mounted within the municipality, where the suburban residential area gives way to the countryside, and the more agricultural side of the municipality.
Høje-Taastrup municipality was not merged with other municipalities on January 1, 2007 as the result of nationwide Kommunalreformen ("The Municipality Reform" of 2007).
