1280 Baillauda (1933 QB) is an outer main-belt asteroid discovered on August 18, 1933, by Delporte, E. at Uccle.

(1280) Baillauda has a diameter of 50.83 km and turns on itself in 12.6 hours.

Its name is not a direct reference to the famous astronomer Benjamin Baillaud, but refers to his son Jules Baillaud, himself an astronomer, who led the observatory of the Pic du Midi de Bigorre from 1937 to 1947.
