Timeships are vessels which have undergone temporal transit. Some timeships were designed and constructed for that purpose, while others underwent time travel through accidental or external forces.
Time-travel pods, Wells-class starships, and Aeon-type ships were built for use as timeships. (TNG: "A Matter of Time"; VOY: "Future's End", "Relativity")
The Federation experimented with sending vessels back in time as early as 2268, but timeships were not regularly built or used until after the 24th century. (TOS: "Assignment: Earth"; TNG: "A Matter of Time")
In the 23rd century, the USS Enterprise used the light-speed breakaway factor to travel through time. (TOS: "Assignment: Earth") By the 29th century, timeships used both temporal rifts and a temporal displacement drive to travel through time. (VOY: "Future's End", "Relativity")
List of timeships
Officially designated timeships
These timeships were either operated exclusively to travel through time, or were sent on time-travel missions in addition to their primary goals.
- Note: the USS Enterprise is included because its mission to 1968 was officially a historical research mission, making it the possibly first ship intended for temporal travel. For details on "accidental" time ventures, see below.

"Unsanctioned timeships"
These starships and vessels were primarily intended for uses other than time travel, however through accidental or unofficial action they traveled to different eras.
