Leerdam (Dutch: [leːrˈdɑm] ⓘ) is a city and former municipality in the western Netherlands, in the province of Utrecht.

The small river Linge, bordered by beautiful water meadows, defines the atmosphere and tone of the landscape.

Several centuries ago Leerdam formed a part of the Vijfheerenlanden domain, before it was raised to the level of County in 1498.

The rich history of Leerdam can be found in well-kept historic buildings such as the Grote Kerk (Great Church), the Hofje van Mevrouw van Aerden (Mrs. Aerden Almshouses, now a museum), the remaining and restored city walls on the Zuidwal and the Oude Raadhuis (Old City Hall).

In South Africa a fort was built by the Dutch East India Company between 1666 and 1679 in the coastal city Cape Town.
