Area codes 619 and 858 are telephone area codes in the North American Numbering Plan (NANP) for most of San Diego County in the U.S. state of California.

Area code 619 was created by a split from area code 714 in 1982, and was the first new area code in California since 707 was added in 1959. Its original numbering plan area was almost all of the southernmost portion of California, from San Diego to the Nevada border.

On March 23, 1997, most of outer northern San Diego County, desert areas and geographical areas in southeastern California split into 760. 

On June 30, 1998, the NANPA approved a request by the California Public Utilities Commission for a two-phase 3-way split of 619 such that phase one would introduce the new 858 area code to northwest San Diego County on June 12, 1999, after which the southern and eastern parts of the county would be split off into a new 935 area code on June 10, 2000, leaving the remaining portion of 619 to serve almost exclusively the city of San Diego. However, after the 858 portion of the split went through, popular and political opposition throughout the country regarding the large number of area code splits being scheduled forced the NANPA to implement 1000-block number pooling, which effectively extended the life of the remaining portion of 619, and the 935 phase of the split was cancelled.

In response to projections that 619 would exhaust in March 2019, the California Public Utilities Commission approved a relief plan that "erased" the 619/858 boundary, turning 619 and 858 into overlay codes for all of the inner portion of San Diego County. This change took effect in June 2018; at that time, 10-digit local calling became mandatory. At the time, 858 was not projected to exhaust for at least 30 years, despite North County's continued explosive growth. Under the most recent projections, San Diego will not need another area code until 2043 at the earliest.

In popular culture
 Professional wrestler and San Diego native Rey Mysterio named his finishing move "The 619" after the area code. A DVD featuring him is titled Rey Mysterio: 619. His entrance theme is called "Booyaka 619" and is performed by fellow San Diego natives P.O.D.
 Football player Reggie Bush painted the number 619 into his eyeblack during games. He explained "When I do that, it's my way of keeping myself humble, of representing my hometown and letting them know I'm not going to forget where I came from."
The switch of 619 to 858 was referenced in the song "Area Code" by Steve Poltz.
