Olivier Chesneau (1972 in Mozé-sur-Louet – May 17, 2014 in Nice[1]) was a French astronomer.

He contributed to a better understanding of several aspects of evolved stars physics, especially planetary nebulae, massive stars and novae.

Among other discoveries, Olivier Chesneau discovered the "peanut star" HR 5171,[2] the fact that novae explode with an hourglass shape already a few days after outburst (e.g. RS Ophiuchi[3]), or the detection of disks in the heart of planetary nebulae.[4]

The Laboratoire J Lagrange at the Côte d'Azur Observatory in France, and ESO established a prize in his memory, The Chesneau Prize.[5]

Minor planet 6065 Chesneau is named in his honor.[6]
