Snillfjord is a former municipality in Trøndelag county, Norway. The municipality existed from 1924 until its dissolution in 2020 when it was split between the municipalities of Hitra, Heim, and Orkland. It was part of the Fosen region. The administrative centre of the municipality was the village of Krokstadøra. Other villages in Snillfjord included Ytre Snillfjord, Hemnskjela, Selnes and Vutudal.
At the time of its dissolution in 2020, the 508-square-kilometre (196 sq mi) municipality was the 209th largest by area out of the 422 municipalities in Norway. Snillfjord was the 394th most populous municipality in Norway with a population of 987. The municipality's population density was 2 inhabitants per square kilometre (5.2/sq mi) and its population had decreased by 3.4% over the last decade.
The municipality of Snillfjord was established on 1 July 1924 when it was separated from the large municipality of Hemne. The initial population was 776. During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1964, the eastern part of the old municipality of Heim (population: 724) and the western part of the neighboring municipality of Agdenes (population: 196) were merged with Snillfjord (population: 681) to form a new, larger municipality of Snillfjord. On 1 January 1995, the Midtun area of Agdenes municipality (population: 21) was transferred to Snillfjord. A road to the area had recently been built, but it connected to Snillfjord and not Agdenes, so it was decided to switch to the other municipality due to the newly opened road connection.On 1 January 2018, the municipality switched from the old Sør-Trøndelag county to the new Trøndelag county.
On 1 January 2020, the municipality of Snillfjord was dissolved and its lands were split between its three neighboring municipalities. The northwestern portion of Snillfjord joined the municipality of Hitra, the southwestern Vennastranda area joined the new municipality of Heim, and the rest joined the new municipality of Orkland.
The municipality was named after the Snillfjorden. The first element is probably an old river name of the Snilldalselva. The river name is derived from snild which comes from the word snjallr which means "fast" (related to German schnell).
