Julius Bauschinger (January 28, 1860 – January 21, 1934) was a German astronomer.
Julius Bauschinger was born in Fürth, the son of the physicist Johann Bauschinger. He studied at the Universities of Munich and Berlin, graduating under the direction of Hugo Hans von Seeliger with a thesis titled "Studies on the motion of the planet Mercury" (1884). In 1882, he was part of a German expedition to Hartford, Connecticut, in order to observe the transit of Venus.
From 1883 he was assistant and observer at the Munich observatory. In 1896 he was named director of the Astronomisches Rechen-Institut and professor of theoretical astronomy in Berlin, a position he held until 1909, when he became director of the Strasbourg observatory.
Bauschinger was dissertation advisor for Alfred Wegener's 1905 doctral thesis in astronomy. Wegener, in 1910, proposed a system of continental drift which was eventually modified and generally accepted as plate tectonics.
From 1920 to 1930 he directed the Leipzig observatory. He died in Munich in 1934.
The minor planet 2306, discovered in 1939, has been named after Bauschinger.
