One light year (abbreviated ly) was a unit of measurement used for establishing distance from one location to another in space. The length of this unit was standardized by the UFP Standards Measurement Bureau. Other spacefaring species, such as the Sheliak, had their own unit of distance. (TOS: "Where No Man Has Gone Before"; TNG: "The Ensigns of Command")
Examples
In the Treaty of Armens (2255), it was stipulated, "Third party assistance may be requested from a Federation Starfleet vessel or a Sheliak Corporate spacecraft if the distance from the vessel to the respective homeworld is greater than five thousand (5.0×103) light years. UFP Standards Measurement Bureau Units. Assistance may also be requested if the vessel is less than 1,000 light years from a standard UFP subspace relay booster station." (TNG: "The Ensigns of Command")
In September 2152, Enterprise NX-01 was in orbit of an uninhabited planet. At this time the ship was over one-hundred light years away from Earth and more than twenty light years away from the Takret homeworld. It encountered a neutronic wave front which spans more than half a dozen light years. (ENT: "The Catwalk")
When the computer identified the numerical sequence sent by the Borg into the Delta Quadrant in 2153, it became pulsar frequencies with geometric light year measurements. (ENT: "Regeneration")
When Commander Benjamin Sisko welcomed the first guest from the Gamma Quadrant in the Alpha Quadrant, a Tosk, he told him that he traveled almost ninety thousand light years through the wormhole. (DS9: "Captive Pursuit")
In 2369, a Vanoben transport was raided two light years away from Deep Space 9. (DS9: "Vortex")
The same year, Sisko told Kai Opaka that the Gamma Quadrant is seventy thousand light years away from Bajor. (DS9: "Battle Lines")
Traveling from 2371 to 2063, Captain Jean-Luc Picard characterized the United Federation of Planets to Lily Sloane as consisting of over one-hundred fifty member worlds spread across eight thousand light years. (Star Trek: First Contact)

Background information
The light year is the distance that light travels in one Earth year. It is approximately equal to 9.46×1012 kilometers, or 5.88×1012 miles.The exact length of a light year depends on the exact length used for one "Earth year". The IAU uses a Julian year of 365.25 days, while other sources may use a Gregorian year of 365.2425 days, or another year altogether.
