Norman Reilly Raine (23 June 1894 – 19 July 1971) was an American screenwriter, creator of "Tugboat Annie" and winner of an Oscar for the screenplay of The Life of Emile Zola (1937).

Raine wrote a series of Tugboat Annie stories for the Saturday Evening Post. In a 1940 news article, it was said he based Tugboat Annie on a female tugboat owner he knew and wanted to write a story about her; however the woman was gentle and Tugboat Annie was not. He also based Tugboat Annie on Marie Dressler after he watched Anna Christie. In 1933 he wrote the screenplay for the film, in which Marie Dressler played Annie and Wallace Beery portrayed Terry, her hard-drinking husband, with whom she traded choice insults.

A 1934 news article said Raine always worked wearing a knit cap and, when he once misplaced it, wore his wife's as a substitute. In 1950, he had been collaborating with writer Guy Gilpatric before he killed himself and his wife after she was diagnosed with breast cancer. In a 1957 article, Raine mentioned that he once wrote a story about the Battle of the Little Bighorn but was rejected by a Hollywood magnate seven times to which Raine said "I'm ready to quit, it's the best I can do. What is there about it that displeases you?" and the magnate responded "I'll tell you, I hate Indians!". He also once wrote for television, three episodes in the series Schlitz Playhouse of Stars.

Subsequently, Raine wrote many other screenplays, among them The Perfect Specimen, God's Country and the Woman, The Adventures of Robin Hood, Each Dawn I Die, The Private Lives of Elizabeth and Essex, Mountain Justice, The Fighting 69th, Men Are Such Fools, Eagle Squadron, Ladies Courageous, We've Never Been Licked, Nob Hill, A Bell for Adano, Captain Kidd and Captains of the Clouds.
