Now or Never is a 1921 American short comedy film starring Harold Lloyd and directed by Hal Roach and Fred C. Newmeyer.

A young woman, who is employed as a nanny to a lonesome child named Dolly, is preparing to take a vacation which will include a long-awaited reunion with her childhood sweetheart.

Her employers are a busy couple who have no time for their small daughter, so the nanny decides—without seeking their permission—to take Dolly with her on her vacation.

He crashes into a barn, loses his money to a tramp, and must complete his journey riding as a stowaway on the undercarriage of a train.

Prints of Now or Never exist in the collections of the UCLA Film and Television Archive and George Eastman House.
