Hornindal is a municipality in the county of Sogn og Fjordane, Norway. It is located in the traditional district of Nordfjord. The administrative centre of the municipality is the village of Grodås. The municipality sits at the eastern end of the lake Hornindalsvatnet, the deepest lake in Northern Europe. The rest of the lake lies inside neighboring Eid municipality.

Hornindal municipality was separated from Eid Municipality in 1867. Hornindal was part of the municipality of Stryn from 1965–1977, but was then separated again.

The European route E39 highway is being re-routed through Hornindal municipality to complete a ferry-free highway route along the western coast of Norway. The Kviven Tunnel was completed in 2012 as part of the new E39 route connecting Hornindal to Volda Municipality in Møre og Romsdal county to the north and avoiding the ferry crossing over the Voldsfjorden.

Since ancient times, Hornindal was a sub-parish (sokn) of Eid prestegjeld (see formannskapsdistrikt). In 1865, Hornindal became a parish of its own and then two years later, on 1 January 1867, Hornindal was established as a separate municipality. At this time, Hornindal had a population of 1,612.

On 1 January 1965, the municipality of Hornindal was dissolved and it was divided between the neighboring municipalities of Eid and Stryn. Navelsaker and Holmøyvik and all of Hornindal west of there (population: 310) was transferred to Eid, and the 1,184 residents to the east of those areas went to Stryn.
