3628 Božněmcová, provisional designation 1979 WD, is a rare-type asteroid from the middle region of the asteroid belt, approximately 7 kilometers in diameter. It was discovered on 25 November 1979, by Czech astronomer Zdeňka Vávrová at Kleť Observatory in the Czech Republic. It is named for Czech writer Božena Němcová.
In the SMASS taxonomy, Božněmcová is a bright O-type asteroid, a rare group with spectra that best fits those of the L6 and LL6 ordinary chondrite-type meteorites. It orbits the Sun at a distance of 1.8–3.3 AU once every 4.04 years (1,477 days). Its orbit has an eccentricity of 0.30 and an inclination of 7° with respect to the ecliptic. It was first identified as 1930 MQ at Lowell Observatory in 1930, extending the body's observation arc by 49 years prior to its official discovery observation at Klet.
In September 2007, a rotational lightcurve of Božněmcová was obtained from photometric observations by American astronomer Brian Warner at his Palmer Divide Observatory in Colorado. Lightcurve analysis gave a well-defined rotation period of 3.335410 hours with a low brightness amplitude of 0.09 magnitude (U=3).
