San Dieguito Heritage Museum
San Dieguito Heritage Museum is a history museum in Encinitas, California, in the United States. Founded in 1988, the museum displays historical photographs and artifacts from Encinitas and the entire San Dieguito area. 
San Dieguito historically comprises seven communities: Cardiff-by-the-Sea, Del Mar, Encinitas, Leucadia, Olivenhain, Rancho Santa Fe, and Solana Beach in the North County area of San Diego County and their adjacent areas, including parts of southern Carlsbad and northwestern San Diego.
The museum is a nonprofit organization that is primarily staffed by volunteers with limited paid staff. The museum is supported by contributions from its members and the wider community at large. 
In 1993, the museum published "San Dieguito Heritage" by Maura Wiegand (). In 1998, the San Dieguito Heritage Museum received a $5,000 challenge grant from the Thomas C. Ackerman Foundation. In 2007, the Rotarians helped the museum spruce up its new location.
In May 2008, the museum opened a ground-breaking new exhibit
