Washington Irving Branch, Public library in Arlington Heights, Los Angeles, United States.

The Washington Irving Branch is a public library in the Arlington Heights neighborhood of Los Angeles. The building holds collections in multiple languages, public computers, and materials for readers of all ages.

The original building from 1926 was designed in Mediterranean Revival style and is still listed on the National Register of Historic Places. The current facility opened in 2000 to better serve the community with updated features.

The branch is named after Washington Irving, the American author of "Rip Van Winkle" and "The Legend of Sleepy Hollow". Its 1926 reading room had exposed wood trusses and rafters, and books sat on thick wooden shelves until the library closed in 1999. The replacement building on Washington Boulevard was dedicated on March 6, 2000.

The current branch at 4117 W. Washington Boulevard was dedicated on March 6, 2000, and covers 12,269 square feet. The Washington Irving Pocket Park opened beside it on July 16, 2022, so a visit can combine the library with the adjacent outdoor space. The original 1926 building at 1802 S. Arlington Avenue is fenced and boarded, so it can only be seen from the street.

The Washington Irving Pocket Park opened on July 16, 2022, beside the 2000 library building on West Washington Boulevard. Councilman Herb Wesson described it as the community, the Council Office and the Recreation & Parks and Library departments working together to use the space more effectively.
