The La Purísima Mission State Historic Park is a historic site and state park in Lompoc, California. It is the site of the Misión la Purísima Concepción de María Santísima (Mission of the Immaculate Conception of Most Holy Mary) founded in December 8, 1787 as the 11th of the 21 Franciscan Missions to be established in the state.

Considered as the most completely restored mission in all of California, the La Purisima Mission State Historic Park still contains the original buildings that it has always had. Visitors can still find at the site the restored and furnished quarters, church, shops, and blacksmith shop. They also have a mission garden, although, it is already designed to represent what the missionaries could have found back when they were first establishing the site.
