3 kpc Arm
A map of the Milky Way Galaxy
The 3 kpc Arm is a collection of stars, planets, nebulae, and other spatial objects that forms the curved "arms" projecting out from the galactic core of the Milky Way Galaxy.
The 3 kpc Arm was shown on Federation star charts in astrometrics aboard the USS Voyager during the later years of its seven-year journey in the Delta Quadrant. (VOY: "Inside Man", et al., display graphic)
In an alternate timeline, the star chart depicting Voyager's flight path home was also displayed in Captain Harry Kim's ready room aboard the USS Rhode Island in 2404. (VOY: "Endgame")

The graphic is shown in legible detail in Geoffrey Mandel's Star Trek: Star Charts (pp. 76-77).
The name "3 kpc" refers to 3 kiloparsecs, or approximately 10,000 light years, as that is how far it extends from the galactic core.
