Gjemnes is a municipality in Møre og Romsdal county, Norway on the Romsdal peninsula. It is part of the Nordmøre region. The administrative centre is Batnfjordsøra, which lies along the Batnfjorden and is a former steamship landing place.

The municipality of Gjemnes was established on 1 September 1893 when parts of Kvernes, Øre, and Frei were merged together. The initial population of the municipality was 934. On 1 January 1965, the municipality of Øre (population: 1,565) and all of Tingvoll west of the Tingvollfjorden (population: 778) were merged together with Gjemnes (population: 697) to form a new, larger municipality of Gjemnes.
The municipality is named after the old Gjemnes farm (Old Norse: Gefnes), since the church was built there in 1893. The meaning of the first element is probably the old river name and the last element is Nes which means "headlands".
