Lalande 21185 was a star in the Alpha Quadrant that was located approximately eight light years from Sol.
In 2364, the location of Lalande 21185 was labeled in a star chart of a stellar neighborhood with Sol at the center. This chart was stored in the USS Enterprise-D library computer. Later that year, the chart was scanned by Outpost 63. (TNG: "The Naked Now", production art; TNG: "The Last Outpost")

Background information[]
This star was only mentioned in writing.
This star's quadrant of origin is inferred based on the position of neighboring locations – 61 Cygni, Alpha Centauri, Procyon, Sol, Tau Ceti, and Wolf 359 – as seen in the star charts appearing in the Star Trek: Discovery episode "Magic to Make the Sanest Man Go Mad" and in the Star Trek: Picard episode "Maps and Legends".
This star chart naming stars within 20 light years of Sol was drawn by Rick Sternbach for the Star Trek Spaceflight Chronology (p. 77) in the late 1970s. This chart showed Earth commercial and exploration routes after the use of warp drive began. There were no commercial or exploration routes to this star.
In 2020, the exoplanet Lalande 21185 b was confirmed to be orbiting this star.
