Cinema 21, Movie theater in northwest Portland, US

Cinema 21 is a movie theater in northwest Portland showing independent films, foreign language works, and documentaries across three screens within a renovated building on Northwest 21st Avenue. The venue features wheelchair accessibility, gender-neutral restrooms, assistive listening devices, closed captioning, and audio description services for select screenings.

The venue opened as the State Theatre in 1925, was called Vista in 1941–1942, then 21st Avenue Theatre from 1942 to 1965, when it took the name Cinema 21. In August 2014 owner Tom Ranieri raised $70,000 on Kickstarter to replace seats over fifty years old and add two screens. In December 2014 the premiere of Wild was held here, attended by Reese Witherspoon and Laura Dern.

Cinema 21 has long backed independent and local filmmakers, and directors including Gus Van Sant, Todd Haynes, Miranda July, Richard Linklater and Steven Soderbergh have presented and discussed their projects on its stage. In December 2014 the theater hosted the premiere and after party for Wild, attended by Reese Witherspoon and Laura Dern; in April 2023 it premiered Tommy Wiseau's second film, Big Shark.

Cinema 21 sits on Northwest 21st Avenue in the Northwest District. The 2014 renovation added two screens alongside the main auditorium, whose seats were replaced through a $70,000 Kickstarter campaign; contributors could bid for naming rights to the auditorium.
