1334 Lundmarka, provisional designation 1934 OB, is a carbonaceous asteroid from the outer region of the asteroid belt, approximately 30 kilometers in diameter. It was discovered on 16 July 1934, by German astronomer Karl Reinmuth at Heidelberg Observatory in southern Germany, and named after Swedish astronomer Knut Lundmark.
Lundmarka is classified as C-type and X-type asteroid by the LCDB and Pan-STARRS, respectively. It orbits the Sun at a distance of 2.6–3.2 AU once every 4 years and 12 months (1,816 days). Its orbit has an eccentricity of 0.10 and an inclination of 11° with respect to the ecliptic. The body's observation arc begins with its official discovery observation at Heidelberg, as no precoveries were taken and no prior identifications were made.
A rotational light-curve of Lundmarka was obtained from photometric observations made at the Australian Oakley Southern Sky Observatory (E09) in September 2014. The light-curve gave a rotation period of 6.250±0.003 hours with a brightness variation of 0.70 in magnitude (U=3-).
