Modjeska Peak, Mountain summit in Santa Ana Mountains, California

Modjeska Peak is the northern summit of the Saddleback landform in the Santa Ana Mountains of Orange County, California, reaching 1,641 metres. It lies within Cleveland National Forest less than a kilometre northwest of the taller Santiago Peak. Its bare summit has no manmade structures, so the Pacific Ocean and San Gabriel Mountains are visible from the top.

The summit was named in 1909 following a campaign by the Ebell Society of Santa Ana to honor Polish actress Helena Modjeska after her death. This naming reflected local efforts to commemorate a cultural figure who had connections to the region.

The peak honors Helena Modjeska, a Polish actress who settled in the area and became part of the local community. Her name reflects the region's connection to her legacy as a cultural figure who shaped the community.

Visitors need a National Forest Adventure Pass for parking at the trailhead and should bring plenty of water for the hike. The route is steep and exposed, so sturdy hiking boots and an early start are recommended to finish before sunset.

Modjeska Peak once carried a Pacific Bell tower for a "wireless cable" television service launched in Southern California in 1996. That tower has since been removed, and most of the range's wireless antennas now sit on neighboring Santiago Peak.
