352 Gisela is an asteroid belonging to the Flora family in the Main Belt that has an unusually high albedo. It was discovered by German astronomer Max Wolf on 12 January 1893 in Heidelberg, and named after his wife. This minor planet is orbiting the Sun at a distance of 2.19 AU with a period of 3.250 yr and an orbital eccentricity of 0.149. The orbital plane is inclined at an angle of 3.38° to the plane of the ecliptic.

Photometric measurements of 352 Gisela during December 1999 were used to produce a light curve showing a sinodic rotation period of 7.49±0.01 h with a brightness variation of 0.32 in magnitude. This period estimate was refined to 7.4796±0.0002 h in 2012.
