The Goethe Link Observatory is an astronomical observatory near Brooklyn, Indiana (USA) owned by Indiana University and operated by the Indiana Astronomical Society. It is named in honour of Dr. Goethe Link, an Indianapolis surgeon, who built it with his private funds. Construction of the observatory started in 1937, and the telescope was first operated in 1939. Link donated the observatory to Indiana University in 1948.
A number of asteroid discoveries were made there, including 1578 Kirkwood. These are credited by the Minor Planet Center under the name "Indiana University," which operated the Indiana Asteroid Program at Goethe Link from 1949 until 1967 using a 10-inch f/6.5 Cooke triplet astrograph. The asteroid 1728 Goethe Link was discovered there on October 12, 1964.
