Gone-Away Lake is a children's novel written by Elizabeth Enright, illustrated by Beth and Joe Krush, and published by Harcourt in 1957. It was a runner-up for the annual Newbery Medal and was named to the Lewis Carroll Shelf Award list in 1970. It tells the story of cousins who spend a summer exploring and discover a lost lake and the two people who still live there.

Enright, the Krushes, and Harcourt produced a sequel published in 1961, Return to Gone-Away, in which the children's family buys a house near Gone-Away.

Gone-Away Lake opens on a train traveling through the countryside of western New York state. Ten-year-old Portia Blake and her six-year-old brother Foster are going to see their favorite cousin, enthusiastic amateur naturalist Julian Jarman. The Jarmans have recently purchased a house in the country. Once there, Portia and Julian spend their days exploring, and one day they discover an abandoned Victorian resort community next to a bog. Elderly siblings Mr. Payton and Mrs. Cheever, the town's only remaining inhabitants, soon become friends with the children, who set up a club in one of the empty houses.

Stories of the days when the bog was a lake called Tarrigo are interspersed with the modern-day adventures of Portia and Julian, who at first keep the lake and their new friends a secret. Foster soon discovers the secret and eventually the rest of the Jarman and Blake families also become acquainted with the charms of Gone-Away and its inhabitants. In Return to Gone-Away, a sequel published in 1961, the Blake family buys and restores a house at Gone-Away.
