Founded in 1927, Sherman Oaks is a neighborhood of the city of Los Angeles, California within the San Fernando Valley region. The neighborhood includes a portion of the Santa Monica Mountains, which gives Sherman Oaks a lower population density than some other areas in Los Angeles.

A partner of the Los Angeles Suburban Homes Company, Gen. Moses Hazeltine Sherman developed Sherman Oaks. The company had subdivided 1,000 acres (400 ha) of land that would become Sherman Oaks. In 1927, each acre was sold for $780. Sherman's other major venture was the Los Angeles Pacific Railroad.

In 1991, a group of homeowners living in the Chandler Estates area successfully petitioned former Los Angeles City Councilmember Zev Yaroslavsky to re-draw the boundaries of Sherman Oaks from Magnolia Boulevard to Burbank Boulevard in the north, and from Coldwater Canyon Avenue to Van Nuys Blvd in the west, with the goal of including their neighborhood. This request was nothing new to the San Fernando Valley; other neighborhoods had either sought to change their names, or sought to attach themselves onto more affluent neighborhoods. Residents in the area argued, however, that the area was originally part of Sherman Oaks, but was labeled Van Nuys instead through the creation of ZIP codes in 1962; a resident produced a property deed to buttress the case.

Just a few weeks after the Chandler Estates area successfully seceded from Van Nuys, Magnolia Woods, a 45 block area bordered by Van Nuys Boulevard on the east and the San Diego Freeway on the west, and between Burbank and Magnolia Boulevards, also successfully petitioned Los Angeles City council member Marvin Braude to secede from Van Nuys and join Sherman Oaks. Petitioners in the area argued that their neighborhood was also part of Sherman Oaks, though they were only able to produce 22 deeds showing so. As a result of this change, Van Nuys Middle School became separated from its namesake neighborhood.

Finally, in 2009, the Los Angeles City council voted to redraw neighborhood boundaries again to allow an area of about 1,800 homes in Van Nuys to be included.

The 1994 Northridge earthquake caused damage in the surrounding area. The Community Redevelopment Agency sought to manage the rebuilding efforts. The homeowners in the Sherman Oaks area later won a lawsuit to prevent the agency from managing efforts.

The neighborhood is roughly bounded by Studio City to the east, Van Nuys to the north, Encino to the west, Bel Air and Beverly Hills Post Office to the south.

As of 2022, according to the Los Angeles Almanac there were estimated to be 66,686 residents of Sherman Oaks.

The racial makeup of the neighborhood was 82% non-Hispanic white, 5% Asian American and 3% African American; 11% were Hispanic or Latino of any race. Other races made up less than 1%.

The Los Angeles Times reported that the 2000 U.S. census counted 61,166 residents in the 9.15-square-mile Sherman Oaks neighborhood, including a wide swath of the Santa Monica Mountains—or 6,687 people per square mile, among the lowest population densities for the city. In 2008, the city estimated that the resident population had increased to 65,436.

In 2000, the percentages of residents aged 19 to 49 and 65 and older were among the county's highest. The percentages of divorced residents and of widows were among the county's highest. The average household size of two people was low when compared to the rest of the city and the county. Renters occupied 58.9% of the housing stock and house- or apartment-owners held 41.1%.

The neighborhood was considered "not especially diverse" ethnically within Los Angeles, with a high percentage of white residents. The breakdown was whites, 73.8%; Latinos, 11.8%; Asians, 5.7%; blacks, 4.4%; and others, 4.4%. Russian (8.4%) and German (7.4%) were the most common ancestries. Iran (14.1%) and Mexico (8.8%) were the most common places of birth for the 26.2% of the residents who were born abroad—an average percentage for Los Angeles.

The neighborhood had a median household income of $69,651 in 2008, which was high for the city of Los Angeles but about average for the county as a whole. (Median household income reports the amount of money earned by the household that falls exactly in the middle of the pack.) The percentage of households that earned $125,000 and up was high for Los Angeles County.
