The Time Machine is a post-apocalyptic science fiction novella by H. G. Wells, published in 1895. The work is generally credited with the popularization of the concept of time travel by using a vehicle or device to travel purposely and selectively forward or backward through time. The term "time machine", coined by Wells, is now almost universally used to refer to such a vehicle or device.

Utilizing a frame story set in then-present Victorian England, Wells` text focuses on a recount of the otherwise anonymous Time Traveller`s journey into the far future. A work of future history and speculative evolution, Time Machine is interpreted in modern times as a commentary on the increasing inequality and class divisions of Wells` era, which he projects as giving rise to two separate human species: the fair, childlike Eloi, and the savage, simian Morlocks, distant descendants of the contemporary upper and lower classes respectively. It is believed that Wells` depiction of the Eloi as a race living in plenitude and abandon was inspired by the utopic romance novel News from Nowhere (1890), though Wells` universe in the novel is notably more savage and brutal.
