The Princess is a serio-comic blank verse narrative poem, written by Alfred Tennyson, published in 1847. Tennyson was Poet Laureate of the United Kingdom from 1850 to 1892 and remains one of the most popular English poets.

The poem tells the story of a heroic princess who forswears the world of men and founds a women's university where men are forbidden to enter. The prince to whom she was betrothed in infancy enters the university with two friends, disguised as women students. They are discovered and flee, but eventually they fight a battle for the princess's hand. They lose and are wounded, but the women nurse the men back to health. Eventually the princess returns the prince's love.

Several later works have been based upon the poem, including Gilbert and Sullivan's comic opera Princess Ida.
