Mount Soledad, Veterans memorial with cross in La Jolla, San Diego, US.

Mount Soledad is an 823-foot (251 m) mountain in La Jolla, San Diego, between Interstate 5 and the Pacific Ocean. Its summit holds a large concrete Christian cross, first built in 1913 and rebuilt twice, the current version dedicated in 1954. The northern and eastern slopes form a sharp escarpment along the Rose Canyon Fault, while Pacific Beach lies on the gentler southern slope. Radio and television transmitters, including KFMB-TV and KGTV, stand on the summit.

A cross was first built on the summit in 1913 and has been rebuilt twice; the current concrete version was dedicated in 1954 as the Mount Soledad Easter Cross, a name shortened in the 1980s. After court challenges in the late 1980s it was designated a Korean War memorial. In July 2015 the Mt. Soledad Memorial Association bought the half-acre beneath it for $1.4 million, and in 2016 the Ninth Circuit dismissed the case as moot.

The name comes from the Spanish word for solitude, reflecting the contemplative purpose of honoring the fallen. The arrangement of thousands of memorial plaques in concentric circles creates a gathering space where people come to remember military service across generations.

Drivers reach the summit by road, and cyclists use routes such as the 3.5-mile Soledad Mountain Road climb from the south or the steep 1.25-mile Hidden Valley Road to Via Capri on the north side. Commercial jets approaching San Diego from Los Angeles begin their downwind leg over the mountain, so aircraft pass low overhead.

The last home lived in by Dr. Seuss stands on the mountain; his widow Audrey Geisel stayed in the house, which has an observation tower locals call the Seuss house, until her death in 2018. An urban legend holds that little people from 1930s Hollywood films such as The Wizard of Oz built miniature houses on the steep slopes, an effect created by the downward perspective.
