Gruber was an unincorporated place in what is now the Rural Municipality of Mossey River, Manitoba. Hersh Girtle was the postmaster at one time. The location was described as 37 miles (60 km) north of Dauphin and 2 miles (3 km) north of Winnipegosis, but another source gives the location as 1.5 miles (2.5 km) south of Winnipegosis.
