The Shri Swaminarayan Mandir is a Hindu temple complex located in Chino Hills, in southwestern San Bernardino County in southern California. The temple belongs to the Bochasanwasi Akshar Purushottam Swaminarayan Sanstha denomination of Hinduism. However it is open to visitors of all faiths.

Constructed from 35,000 pieces of hand carved Italian Carrara marble and Indian Pink sandstone, it was completed in 2012 and is the first earthquake-proof Mandir in the world. Approximately 900 volunteers donated 1.3 million man hours to the construction.

Pramukh Swami Maharaj, the former spiritual leader of BAPS visited California in 1977. During his visit, he encouraged a small group of individuals to hold regular assemblies. He returned nearly every year, nurturing and inspiring devotees.

The local group made a proposal in 1996 to build a traditional stone temple fulfilling Pramukh Swami's vision and accommodating their growing congregation.

The 20-acre site contains a 91-foot lotus-shaped pond, five pinnacles, two large domes, four balconies, 122 pillars and 129 archways. From the external walls and domes to the inside pillars and ceilings, the Mandir is etched with intricate carvings in marble and sandstone. The 6,600 hand-carved motifs depict a mosaic of tales of inspiration, devotion and dedication, along with historical figures from Hinduism. Artisans created the carvings in India with great love, skill and patience before the pieces were shipped to Chino Hills.
