972 Cohnia is a minor planet orbiting the Sun, one of several such in the asteroid belt. It was discovered on 18 January 1908 by a team in Heidelberg led by Max Wolf. In 2007, lightcurve data showed that Cohnia rotates every 18.472 ± 0.004 hours.^[2]

It is named after the German astronomer Fritz Cohn.
