Corona del Mar (Spanish for “Crown of the Sea”) is a neighborhood in Newport Beach, California. It generally consists of all land on the seaward face of the San Joaquin Hills south of Avocado Street to the city limits, as well as the development of Irvine Terrace, just north of Avocado. Beaches in the area include Corona del Mar State Beach as well as Crystal Cove State Park south of Corona del Mar, accessible by paths winding down a steep hillside.

Settled early in the 20th century, the older area of Corona del Mar consists mostly of closely-spaced, free-standing, detached single family houses of varying architecture, concentrated along Pacific Coast Highway (also known as “PCH” or State Route 1). Newer developments in Harbor View Hills consist of California ranch style houses, many with expansive ocean views.

Corona del Mar has no locally administered municipal government, but receives all municipal level services from the City of Newport Beach, and has a representative to the Newport Beach City Council. It is unusual in that although it is a part of an incorporated city, the post office accepts a mailing address of Corona del Mar for those residents living in the 92625 ZIP Code, and the community has its own Chamber of Commerce.
