Dorsum Zirkel is a wrinkle ridge at 28°06′N 23°30′W / 28.1°N 23.5°W / 28.1; -23.5 northeast of Mons La Hire in Mare Imbrium on the Moon. It is 193 km long and was named after Ferdinand Zirkel in 1976.[1][2]

Two small craters, La Hire A and B, lie on either side of the dorsum. The large crater Lambert is to the southeast, and the smaller McDonald is to the northeast.
