Modjeska Canyon is an unincorporated community and census designated place (CDP) on the western slope of the Santa Ana Mountains in eastern Orange County, California.

The community of Modjeska is very tight knit, hosting several in-canyon events, such as pot lucks, dance lessons, movie nights at the park, Fourth of July parades, as well as Christmas and Halloween parties.

They also hold events for non-residents to come and enjoy, such as an arts and crafts fair held in early spring at the Tucker Wildlife Sanctuary.

[11] The Brotherhood of Eternal Love was incorporated as a non-profit organization in Modjeska on Oct 26, 1966 — a few months before John Griggs and other founding members relocated to the Woodland Drive neighborhood of Laguna Beach, CA (later known as 'Dodge City').

Mandatory evacuations were issued prior to President George W. Bush declaring the site an emergency.
