Kalgan is a small town and locality of the City of Albany in the Great Southern region of Western Australia.

The western part of Gull Rock National Park is located within Kalgan.

Land was set aside for a townsite in 1837[5] and was sparsely settled, with approximately a dozen people living in the area in 1900.

[5] The Upper Kalgan Hall was constructed in 1912 and became a focal point for the community.
