"The Girl on the Boat" (1922) is a novel by P. G. Wodehouse. The girl from the title is the red-haired, dog-loving Wilhelmina "Billie" Bennett, and the three men are: Bream Mortimer, a long-time and long-suffering suitor of Billie's; Eustace Hignett, a shy poet who is cowed by his domineering mother but secretly engaged to Billie at the opening of the tale; Sam Marlowe, Eustace's dashing cousin, who falls in love with Billie "at first sight". The four of them find themselves together on an ocean liner sailing for England. Also on board is a capable young woman, Jane Hubbard, who is in love with Eustace. Wodehousian funny stuff ensues, with happy endings for all except Bream Mortimer.

Sir Pelham Grenville Wodehouse (1881-1975) was an English author and one of the most widely read humorists of the 20th century.
