3850 Peltier, provisional designation 1986 TK2, is a Florian asteroid and suspected interloper from the inner regions of the asteroid belt, approximately 4 kilometers in diameter. It was discovered on 7 October 1986, by American astronomer Edward Bowell at Lowell's Anderson Mesa Station, near Flagstaff, Arizona. It is named for astronomer Leslie Peltier.

In the SMASS taxonomy, Peltier is a V-type asteroid but possesses the orbital characteristics of a member of the Flora family, which is one of the largest groups of stony S-type asteroids in the main-belt. It is therefore thought to be an unrelated interloper that does not origin from the Flora family's parent body. Peltier orbits the Sun at a distance of 1.9–2.6 AU once every 3 years and 4 months (1,220 days). Its orbit has an eccentricity of 0.16 and an inclination of 5° with respect to the ecliptic. In 1949, it was first identified as 1949 PC at Johannesburg. The body's observation arc begins at Crimea-Nauchnij in 1979, when it was identified as 1979 OX13, 10 years prior to its official discovery observation at Anderson Mesa.

A rotational light-curve of Peltier was obtained by Czech astronomer Petr Pravec at Ondřejov Observatory in October 2006. Lightcurve analysis gave a rotation period of 2.4287 hours with a brightness variation of 0.09 magnitude (U=2). In December 2013, photometric observations by Australian amateur astronomer Julian Oey gave a concurring period of 2.4289 hours and an amplitude of 0.10 magnitude (U=3).
