Sigi Regency is a regency of Central Sulawesi, Indonesia. It was created on 21 July 2008 by splitting off the southern districts from Donggala Regency. It lies upstream on the Palu River, and immediately south of Palu city, the provincial capital. The regency is almost landlocked; it has a small coastline between Palu city and the western part of Donggala regency. It covers an area of 5,196.02 km2 and had a population of 215,030 at the 2010 Census and 239,421 at the 2020 Census; the official estimate as at mid 2024 was 270,189 (comprising 138,405 males and 131,784 females). The principal town lies at Sigi Biromaru.

The northern part of the Sigi Regency was one of the areas in northwest Sulawesi most affected by the 2018 earthquake and tsunami in Sulawesi. Dozens of people were reported to have been killed by the earthquake and there were reports of "massive liquification" which caused homes to be swept away.
