Walter Lang (born August 10, 1896 - died February 7, 1972) was an American film director.

Born in Memphis, Tennessee, as a young man he went to New York City where he found clerical work at a film production company. The business piqued his artistic instincts and he began learning the various facets of filmmaking and eventually worked as an assistant director. However, Lang also had ambitions to be a painter and left the United States for a time to join the great gathering of artists and writers in the Montparnasse Quarter of Paris, France. Things did not work out as Lang hoped and he eventually returned home and to the film business.

In 1926, Walter Lang directed his first silent film, The Red Kimona. In the mid 1930s, he was hired by 20th Century Fox where, as a director, he "painted" a number of the spectacular colorful musicals for which Fox Studios became famous for producing during the 1940s. One of Lang's most recognized films is his 1956 epic The King and I for which he was nominated for the Academy Award for Directing.

Walter Lang died in 1972 in Palm Springs, California and was interred in the Inglewood Park Cemetery in Inglewood, California.

For his contribution to the motion picture industry, Walter Lang has a star on the Hollywood Walk of Fame at 6520 Hollywood Blvd.

Walter Lang entered the film industry in New York when he got a job as a clerk in the office of a film production company. He worked his way up to assistant director, and directed his first film in 1926. By the time sound arrived Lang was already a well-regarded director, but he left the business at that time to try his hand as an artist in Paris. His venture into that medium was unsuccessful, and he returned to Hollywood a few years later. In the mid-'30s Lang was hired at 20th Century-Fox, and it was there he found his niche. He was one of the talents responsible for the glossy, splashy Technicolor musicals Fox was famous for in the 1940s and 1950s, films such as Tin Pan Alley (1940), Moon Over Miami (1941), Coney Island (1943) and There's No Business Like Show Business (1954). Always well respected by his contemporaries (Betty Grable once said that he was one of the few true gentlemen she had ever met), Lang ended his long and productive career in 1961 with Snow White and the Three Stooges (1961).
