Rock is an unincorporated community in Delta County, Michigan, United States.

Rock is located in Maple Ridge Township along M-35 and the Canadian National Railway, 16.5 miles (26.6 km) north-northwest of Gladstone.

J.R. Steele bought land in the community from the railroad in 1866 and settled there, and George English built a store there in the same year.

The community was originally called Malton Spur, and a post office called Malton operated from March 28, 1879, to April 30, 1883; Henrietta Crawford served as postmaster of this post office.

The community was then renamed Maple Ridge, but changed its name again to Rock when applying for a new post office.
