Landmark Theatres is a movie theatre chain founded in 1974 in the United States. It was formerly dedicated to exhibiting and marketing independent and foreign films. Landmark consists of 34 theatres with 176 screens in 24 markets. It is known for both its historic and newer, more modern theatres. Helmed by its President, Kevin Holloway, Landmark Theatres is part of Cohen Media Group (as of 2018^[update]).

Landmark Theatre Corporation began as Parallax Theatres and was founded in 1974 by Kim Jorgensen with the opening of the Nuart Theatre in Los Angeles, the Sherman in Sherman Oaks, the Rialto in South Pasadena, and the Ken in San Diego. Steve Gilula and Gary Meyer became partners in 1976, as the chain expanded as Landmark.

In 1976, the River Oaks Theatre in Houston (which originally opened in 1939) and the single-screen Oriental Theatre in Milwaukee were acquired. The Oriental originally opened in July 1927 and was the only standard movie palace ever built to incorporate East Indian décor. The Harvard Exit Theatre in Seattle was acquired in 1979. The film programming in Landmark Theatres was a mix of repertory/revival double-features that changed daily. This mix also included smaller independent and foreign films and allowed Landmark to grow into the largest repertory/revival movie-theater circuit in the nation by the end of that decade.^{[citation needed]}

In the early 1980s, Landmark reoriented most of their theatres to exhibit first-run specialized, foreign, and re-released classics on longer, open-ended runs. Larger single screens were converted into two or three-screen theatres while preserving the external architecture.

In 1981, Landmark acquired the Neptune Theatre in Seattle. The following year, Landmark merged with Movie, Inc. of Santa Fe, NM, which also focused on showcasing foreign, alternative, and classic films. In 1988, The Oriental Theatre in Milwaukee underwent a conversion into a triplex by adding two theaters underneath the balcony, while preserving the original artwork of the main auditorium. Additionally, Landmark opened Canal Place Cinema (4 screens) on the edge of New Orleans' French Quarter, marking its first new build. In 1989, Landmark merged with the Seven Gables theater circuit from Seattle and Portland. Subsequently, Heritage Entertainment acquired Landmark.

In the early 1990s, Landmark began renovations of its historic buildings and began developing new multiplex theaters of its own. The new locations included the Westside Pavilion in Los Angeles, the Embarcadero in San Francisco's Financial District, the Embassy in Waltham near Boston, the Plaza Frontenac in St. Louis, the Century Center in Chicago, and the Renaissance in Highland Park near Chicago. In 1991, the Clay Theatre of San Francisco was purchased. In 1998, Landmark was acquired by Silver Cinemas and began operating a small group of discount theaters including the Bell Road, the Superstition, The Yukon, the Golden Triangle, the Macomb, the Joliet, the Budget South, the East Town Green Bay, the Market Square and the Poughkeepsie theaters. Landmark was acquired by the Samuel Goldwyn Company in 1990.

Landmark was brought out of Silver Cinemas' bankruptcy by Oaktree Capital, allowing the construction and opening of the Sunshine, Bethesda Row and E Street Cinemas. On September 24, 2003, Landmark was acquired by Todd Wagner and Mark Cuban's 2929 Entertainment, the Magnolia Pictures exhibition wing folded into Landmark Theatres. Digital Cinema was introduced.

In 2005, Landmark was the first exhibition circuit to deploy Sony 4K cinema; in-theater digital signage was introduced. In Indianapolis, Landmark opened the Keystone Art Cinema & Indie Lounge. The cinema had 7 auditoriums; the lounge featured plasma televisions and allowed all moviegoers to bring their drinks into the auditoriums. And, the Inwood Theater and Nuart Theater were renovated.
