The 6-acre (2.4 ha) Gardens at Heather Farm are a set of gardens located at Heather Farm Park in Walnut Creek, California, United States. The gardens have a view of Mount Diablo, and are open to the public 7 days a week during daylight hours.

In 1967, Walnut Creek city park director Ruth Wallis called a meeting with the presidents of three local garden clubs to discuss the possibility of a gardening association for Walnut Creek. This group then asked the city for the use of part of the planned Heather Farm Park. The Heather Farm Garden Center Association was incorporated in 1971. Members of HFGCA included Philip and Ruth Bancroft, who donated land for Heather Farm Park and founded the Ruth Bancroft Garden. A groundbreaking ceremony for the gardens was held on August 12, 1979. The HFGCA's headquarters, the Heather Farm Garden Center building, opened in 1983 after being funded by plant sales, donations, and grants.
