Jyderup is an old town, with a population of 4,324 (1 January 2024),[2] in Holbæk Municipality, northwestern Zealand in Denmark.

It is situated roughly halfway between the larger cities of Kalundborg and Holbæk on the west and east, respectively, and is surrounded by forest and farmland.

The southwestern part was built when the railroad was constructed in the early 1900s, and contains most of the shops and stores in the town.

In early 2008, the town library was also moved to this part, when the townhall building stood empty, after Tornved Municipality became part of Holbæk Municipality in 2007, and the local authority was moved out of the town for the sake of centralization.
