(Little House: A New Beginning in its ninth and final season) 

is an American Western historical drama television series about the Ingalls family, who live on a farm on Plum Creek near Walnut Grove, Minnesota, in the 1870s–90s. Charles, Caroline, Laura, Mary, and Carrie Ingalls are respectively portrayed by Michael Landon, Karen Grassle, Melissa Gilbert, Melissa Sue Anderson, and twins Lindsay and Sydney Greenbush. The show is loosely based on Laura Ingalls Wilder's best-selling series of Little House books.

In 1972, with the encouragement of his wife and daughter, television producer and former NBC executive Ed Friendly acquired the film and television rights to Wilder's novels from Roger Lea MacBride and engaged Blanche Hanalis to write the teleplay for a two-hour motion picture pilot. Friendly then asked Michael Landon to direct the pilot; Landon agreed on the condition that he may also play Charles Ingalls. The pilot, which first aired on March 30, 1974, was based on Laura Ingalls Wilder's third Little House book, Little House on the Prairie. The rest of the regular series premiered on the NBC network on September 11, 1974, and last aired on May 10, 1982.

During the 1982–83 television season, with the departure of Landon and Grassle, a sequel series, generally considered Season Nine for syndicated packages, was broadcast with the new title Little House: A New Beginning.
