Lalande 21185 is a star in the constellation of Ursa Major, relevant for being the brightest red dwarf observable in the northern hemisphere (only AX Microscopii and Lacaille 9352, in the southern hemisphere, are brighter). Despite this, and although relatively close by, it is (as all red dwarves) very dim, being only magnitude 7.5 in visible light and thus too dim to be seen with the unaided eye. The star is visible through a small telescope or binoculars.

At approximately 8.31 light-years (2.55 parsecs) away it is one of the nearest stars to the Solar System; only the Alpha Centauri system, Barnard's Star, and Wolf 359 and the brown dwarfs Luhman 16 and WISE 0855−0714 are known to be closer. Because of its proximity it is a frequent subject for astronomical surveys and other research and thus is known by numerous other designations. Research papers most commonly use the designations BD+36 2147, Gliese 411, and HD 95735 to refer to this star. In approximately 19,900 years Lalande 21185 will be at its closest distance of about 4.65 ly (1.43 pc) from the Sun.
