The Time Machine is an 1895 dystopian post-apocalyptic science fiction novella by H. G. Wells about a Victorian scientist known as the Time Traveller who travels to the year 802,701. 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's 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, The Time Machine is interpreted in modern times as a commentary on the increasing inequality and class divisions of Wells's 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's depiction of the Eloi as a race living in plenitude and abandon was inspired by the utopic romance novel News from Nowhere (1890)
