The Sea is My Brother is a novel by the American author Jack Kerouac, published in 2011. The novel was written in 1942 and remained unpublished throughout Kerouac's lifetime The plot and its characters are based on Kerouac's brief experience in United States Merchant Marine during World War II.

In 1942, Kerouac served just eight days in the US Merchant Marine, but his brief service nonetheless inspired him to write Sea.The author, who was 20 years old when Sea was written, allegedly thought that the book was "a crock [of shit] as literature",and apparently did not bother to shop it around to publishers. Dawn Ward, editor of the Penguin edition of The Sea is my Brother, holds that while the novel is not the same as the great work Kerouac produced later in his life, it illuminates Kerouac's early development as a writer. "It was referred to briefly in letters, but nothing that led anyone to believe that there was this really large volume ... This book is really quite important as it shows how Jack developed his writing process."
