(3181) Ahnert is an asteroid of the main belt that was discovered on March 8, 1964 by the German astronomer Freimut Börngen at the Thuringian State Observatory in Tautenburg at a brightness of about 16 mag. Subsequently, the asteroid could already be detected on recordings made in March 1931 at the Lowell Observatory , and in 1932, 1936, 1942, 1951 and 1964 at various other observatories.
The asteroid was named after the German astronomer Paul Oswald Ahnert (1897–1989). He has been researching at the Sonneberg observatory since 1938 and since 1949 has been the editor of the astronomical yearbook Calendar for Star Friends and other publications that contributed to the popularization of astronomy.
