Cahuenga Peak, Mountain summit in Griffith Park, Los Angeles, United States.

Cahuenga Peak is the highest summit in Griffith Park, Los Angeles, and the 12th-highest named peak in the Santa Monica Mountains, standing just west of the Hollywood Sign at 555 meters. Its top gives a 360-degree panorama of the Los Angeles Basin and the San Fernando Valley.

Howard Hughes purchased the peak in the 1940s intending to build a residence for actress Ginger Rogers, but the property remained undeveloped. It eventually became protected land as part of the public park system.

The peak became part of Griffith Park after a public campaign that temporarily modified the Hollywood Sign. This effort showed how local communities can protect natural spaces from development.

The Aileen Getty Ridge Trail reaches the summit from the east, via Mount Lee, or from the west, via Burbank Peak. The climb is steep and exposed, so carry water and wear sturdy shoes. The summit sits just west of the Hollywood Sign.

The peak's 138-acre ridge parcel was bought by Chicago investors in 2002 for $1.675 million, and they later sought $22 million for it. The Trust for Public Land draped the Hollywood Sign to read "SAVE THE PEAK"; final-hour gifts of $500,000 from the Louis Comfort Tiffany Foundation and Aileen Getty and $900,000 from Hugh Hefner closed the purchase, and in July 2010 over 100 acres were added to Griffith Park.
