Finsch is a relatively small lunar impact crater in the mid-part of Mare Serenitatis that has been almost completely (other than the crest of the rim) covered by the mare, forming a ghost crater in the lava plain. It was named after German zoologist Otto Finsch. It is located to the south-southeast of the crater Sarabhai and northeast of Bessel.
