Winkler is a small lunar impact crater on the far side of the Moon. It is located about one crater diameter to the south-southeast of Dunér. This feature forms a circular, cup-shaped depression in the surface. A small, relatively fresh crater lies across the eastern rim.
The crater was formally named by the IAU in 1970 after German rocketry scientist Johannes Winkler.Winkler, Gazetteer of Planetary Nomenclature, International Astronomical Union (IAU) Working Group for Planetary System Nomenclature (WGPSN)
