Gregory Heights Library, Public library in Northeast Portland, United States.

Gregory Heights Library is a branch of the Multnomah County Library at N.E. 79th Avenue and Sandy Boulevard in Portland, Oregon. The 5,997-square-foot building, designed by Farnham and Peck, opened in 1966 and has a capacity of 20,000 volumes.

The library began in 1938 as a reading room at 3448 N.E. 72nd Avenue. In 1956 the Library Association of Portland replaced it with a bookmobile, and in 1962 approved a new branch. The current building, designed by Farnham and Peck, opened on February 24, 1966, at a cost of $83,000. It closed in July 1998 for renovation and reopened on March 2, 1999, with Thomas Hacker and Associates as architect.

In the 1980s the branch added Southeast Asian materials in Vietnamese and Cambodian, a response to the neighbourhood's changing residents. Those language collections remain part of what the library holds today, alongside its general lending stock.

Visitors should use the main entrance on Sandy Boulevard and check opening hours in advance before planning a trip. The community spaces can be reserved through staff, and there is ample room for working, studying, or browsing throughout the building.

The 1996 bond measure that funded the 1998–1999 renovation was approved by Multnomah County voters countywide, not by the Gregory Heights neighborhood alone. Thomas Hacker and Associates designed that renovation; Farnham and Peck had designed the 1966 building. The branch closed again in 2023–2024 for work paid for by a 2020 building bond.
