Morowali Regency is a regency of Central Sulawesi Province of Indonesia. It covers an area of 5,472 km and the districts now within the regency had a combined population of 102,228 at the 2010 Census; the regency population at the 2020 Census was 161,727; the official estimate as at mid 2023 was 170,450 (comprising 93,793 males and 76,657 females). The administrative centre is at the town of Bungku. The Regency includes the far-flung Menui Islands (Kepulauan Menui), lying to the southwest of the rest of the province.

On 4 October 1999, Morowali Regency was created out of a portion of Poso Regency. At that time it was composed of the southeastern fourteen districts from the Poso Regency.

On 12 April 2013 this Morowali Regency was in turn divided into two Regencies; the seven northernmost districts were split off to form a new North Morowali Regency (Morowali Utara) covering nearly two-thirds of the area of the then Morowali Regency, while the seven southernmost districts were retained as the residual Morowali Regency, although two additional districts were created by the division of existing ones.

Morowali Regency contains rich deposits of high-quality nickel, a vital material needed to manufacture lithium batteries. Starting in the 2010s and into the 2020s, the thriving nickel industry in Morowali has resulted in a large increase in the region's GDP (300% increase between 2013 and 2019), but the expansion of the extraction industry has also caused environmental degradation. From 2014 to 2020, over US$6.5 billion in foreign direct investment has flowed into the construction of nickel smelters and other downstream processing activities in Morowali Regency. Morowali is the site of an industrial park, the Morowali Industrial Park, specifically earmarked for refining activities. In Morowali, GDP more than tripled in just six years from Rp 6.9 trillion (US$480 million) in 2013 to Rp 24.3 trillion (US$1.7 billion) in 2019, almost all of it driven by investment in downstream nickel processing. As of 2021, the largest foreign investors were American, Chinese, and Japanese companies, while the government of Indonesia is attempting to build a domestic battery industry.

The growth of this facility has resulted in the rapid expansion in the population, particularly in Bahodopi District where the mine is situated. The increased workforce migrating into the area has been largely male, resulting in a substantively high gender ratio in the regency.

The Morowali Regency was divided (following the creation of the separate North Morowali Regency in 2013) into seven districts (kecamatan), but two further districts (Bungku Pesisir and Bungku Timur) were later created. These are all tabulated below with their areas and their populations at the 2010 Census and 2020 Census, together with the official estimates as at mid 2022. The table also includes the location of the district headquarters, the numbers of administrative villages in each district (totaling 126 rural desa and 7 urban kelurahan), and its postal codes.
