Beyond the Horizon is a play written by American playwright Eugene O'Neill. Although he first copyrighted the text in June 1918, O'Neill continued to revise the play throughout the rehearsals for its 1920 premiere. His first full-length work to be staged, Beyond the Horizon won the 1920 Pulitzer Prize for Drama.

The play takes place on a farm in the Spring, and then moves forward three years later, in the Summer, and finally five years later, in late Fall. The play focuses on the portrait of a family, and particularly only two brothers Andrew and Robert. In the first act of the play, Robert is about to go off to sea with their uncle Dick, a sea captain, while Andrew looks forward to marrying his sweetheart Ruth and working on the family farm as he starts a family.
