The 5th Avenue Cinema is a two-screen, 35-millimeter projection theater at 510 Southwest Hall Street in Portland, Oregon, in the United States, owned by Portland State University (PSU) and operated by the student-managed PSU Film Committee.

The cinema opened in October 1970, under the name Cine-Mini Theater in rented space formerly used by the Portland State University Bookstore.

[1] The small theater was not a profitable first-run venue, however, and soon it began showing old movies and midnight movies, including the first public screening of "The Rocky Horror Picture Show" in 1975.

[2] The name was changed to 5th Avenue Cinema in 1973, although the entrance remained on Southwest Hall Street.

[3] Almost from the beginning, the cinema worked with the PSU Film Committee to select programming that would appeal to students.
