(720) Bohlinia is an asteroid of the main belt that was discovered on October 18, 1911 by the German astronomer Franz Kaiser in Heidelberg .

The asteroid was named after the Swedish astronomer Karl Petrus Theodor Bohlin (1860–1939).

It belongs to the Koronis - asteroid family , a group of asteroids that after (158) Koronis is named.

A group of astronomers, including Lucy d'Escoffier Crespo da Silva and Richard P. Binzel , used observations from 1998 to 2000 to determine the spin-vector alignment of these asteroids. The joint work resulted in the development of 61 new individual rotating light curves to complement previously published observations.

Binzel and Schelte Bus further expanded their knowledge of this asteroid in a lightwave study published in 2003. This project was known as the Small Main-belt Asteroid Spectroscopic Survey, Phase II, or SMASSII, which built on an earlier study of the main-belt asteroids. The spectrum data of the visible wavelength (0.435-0.925 µm) were collected between August 1993 and March 1999.
