Cauchy is a small lunar impact crater on the eastern Mare Tranquillitatis. It was named after French mathematician Augustin-Louis Cauchy.^[1] It is circular and symmetric, with a small interior floor at the midpoint of the sloping inner walls. Due to the high albedo of this bowl-shaped formation, it is particularly prominent at full Moon.

Cauchy lies between the Rupes Cauchy and the Rimae Cauchy, as described below.

South of Rupes Cauchy are two lunar domes designated Omega (ω) Cauchy and Tau (τ) Cauchy. They lie to the south and southwest of Cauchy respectively. Each lunar dome has a small depression at its crest, which is likely to be a volcanic vent rather than an impact crater. The vent at the top of Omega Cauchy is called Donna.
