Belaruskali (Belarusian: Беларуськалій, Russian: Беларуськалий) is one of the largest state-owned companies of Belarus. It is one of the largest producers of potash fertilizers in the world, accounting for 20% global supply as of 2019.

Belaruskali is the largest single taxpayer in Belarus and an important source of foreign currency of the Belarusian government. As of 2015, it accounted for 11% of tax revenues of Minsk Region.

Most of Belaruskali's production is exported to China.

The company was established in 1958 and comprises four production units, as well as auxiliary shops and service departments. The Belarusian Potash Company is the main distributor of potash fertilizers produced by Belaruskali.

In 2020, four thousand workers of Belaruskali have declared a strike as part of mass peaceful nationwide protests that followed a controversial presidential election, demanding resignation of Alexander Lukashenko and new democratic elections. There have been cases of miners cuffing themselves underground as part of the strike.

According to reports, Belaruskali management threatened and put psychological pressure on the strikers. Belaruskali paid extra bonuses to workers not participating in the strike.

The Belarusian authorities arrested and imposed 15-day prison sentences on some of the striking workers at Belaruskali. Four activists of the Belaruskali labour union - Siarhei Charkasau, Pavel Puchenia, Yury Korzun and Anatol Bokun - were arrested after the strike began. 49 Belaruskali workers were fired for participating in the strike, several had to flee from the country.

The arrested activists were later released following an international solidarity campaign, fired workers were reinstated following inquiries from Yara International, the largest trader of Belaruskali's products, regarding worker rights violations at Belaruskali.
