Corona del Mar (Spanish, "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. Immediately south of Corona del Mar is Crystal Cove State Beach, an expanse of beach 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 California 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.
