HNLMS Jacob van Heemskerk was a Tromp-class light cruiser of the Royal Netherlands Navy, named after Admiral Jacob van Heemskerk (1567–1607). She was commissioned on May 10, 1940, when Nazi Germany invaded the Netherlands. However, as she was not finished she was sent to the UK, where she was refitted as an air defence cruiser.

She saw extensive action during World War II, mostly in convoy duties.

Jacob van Heemskerk was the last of the two Tromp-class cruisers. The other ship was the Tromp.
