1145 Robelmonte is a main belt asteroid orbiting the Sun. Approximately 23 kilometers in diameter, it makes a revolution around the Sun once every 4 years. It was discovered by Eugène Joseph Delporte on February 3, 1929.^[1] It was named after Robelmont, the village in Belgium where astronomer Sylvain Arend was born. Robelmonte is the feminine form. Through an error, the names intended for 1127 Mimi and 1145 Robelmonte had been switched, and each name had been proposed by the discoverer of the other asteroid. The asteroid's provisional designation was 1929 CC.^[2]

Measurements of the lightcurve made in 2010 give a rotation period of 9.01 ± 0.01 hours. It has a diameter of 23.2 km.^[3]
