Jøssund is a former municipality in the old Sør-Trøndelag county, Norway. The municipality existed from 1896 until its dissolution in 1964. The 79-square-kilometre (31 sq mi) municipality encompassed northern coastal area of the present-day municipality of Bjugn in Trøndelag county. The main church for Jøssund was Jøssund Church in the village of Jøssund which was the administrative centre of the municipality. Other villages in Jøssund included Lysøysundet and Vallersund.
The municipality of Jøssund was established on 1 January 1896 when it was split off from the large municipality of Aafjord. Initially, Jøssund had a population of 1,529. During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1964, the municipality of Jøssund (population: 1,917) was merged with the neighboring municipalities of Bjugn (population: 1,240), Nes (population: 1,107), and the northern part of Stjørna (population: 676) to form a new, larger municipality of Bjugn.
