Security Trust, also known as Hollywood Savings and Loan, is a historic bank building with attached retail storefronts located at 7051-7055 W Hollywood Blvd., on the corner of Hollywood Boulevard and Sycamore Avenue, in Hollywood, California.

Security Trust was built in 1928 by John and Donald Parkinson, the duo responsible for some of Los Angeles's most notable landmarks, including Union Station and the Memorial Coliseum. Originally a one-story bank building with three attached one-story storefronts, Security Trust features a Beaux-Arts design, with the bank building's central entryway flanked by two colossal Corinthian columns.

Sometime after 1980, additional stories were added to the building.

In 1984, the Hollywood Boulevard Commercial and Entertainment District was added to the National Register of Historic Places, with Security Trust and its attached storefronts listed as a separate contributing properties in the district.

In 1995, the Church of Scientology bought the building for $1.6 million, to be owned by church affiliate Author Services Inc. The building is currently used for readings of L. Ron Hubbard's pulp fiction and also to house a library of Hubbard's novels and short-story collections.
