109 Felicitas is a dark and fairly large main-belt asteroid. It was discovered by German-American astronomer C. H. F. Peters on 9 October 1869, and named after Felicitas, the Roman goddess of success.<ref name="Schmadel2012"/> The only observed stellar occultation by Felicitas is one from Japan on 29 March 2003.<ref>Observed minor planet occultation events, version of 2005 July 26</ref>

This body is orbiting the Sun with a period of 4.43 years and an eccentricity (ovalness) of 0.3. Its orbital plane is inclined by 7.9° from the plane of the ecliptic. 109 Felicitas is classified as a carbonaceous GC-type asteroid. It is spinning with a rotation period of 13.2 hours. During 2002, 109 Felicitas was observed by radar from the Arecibo Observatory. The return signal matched an effective diameter of 89 ± 9 km. This is consistent with the asteroid dimensions computed through other means.<ref name="icarus186_1_126"/>
