The Song of the Lark is the third novel by American author Willa Cather, written in 1915. It is generally considered to be the second novel in Cather's Prairie Trilogy, following O Pioneers! (1913) and preceding My Ántonia (1918).

The book tells the story of a talented artist born in a small town in Colorado who discovers and develops her singing voice. Her story is told against the backdrop of the burgeoning American West in which she was born in a town along the rail line, of fast-growing Chicago near the turn of the twentieth century, and of the audience for singers of her skills in the US compared to Europe. Thea Kronborg grows up, learning herself, her strengths and her talent, until she reaches success.

The title comes from a painting of the same name by Jules Breton in 1884 and part of the collection of the Art Institute of Chicago.
