Bobillier is a tiny, cup-shaped lunar impact crater in the southwest part of Mare Serenitatis. The outer ejecta of this impact has subsequently been flooded by mare material around 100 m thick. Bobillier lies to the north-northwest of the crater Bessel. To the south and west is a wrinkle ridge designated Dorsum Buckland.
Previously identified as Bessel E, this crater is named after French geometer Étienne Bobillier. Its designation was adopted by the International Astronomical Union in 1976.
