Tata Chemicals Magadi (formerly The Magadi Soda Company) is Africa's largest soda ash manufacturer and one of Kenya's leading exporters. It also manufactures salt from the waters of Lake Magadi for the Kenyan market. The company was established in 1911.

The company employs over 450 people at its facilities at Lake Magadi, 120km southwest of Nairobi in Kenya. Trona ore is recovered from surface deposits at the base of the Rift Valley, at Lake Magadi, and converted into soda ash. The soda ash is transported by rail to the Port of Mombasa for onward shipping.

Soda ash is an essential constituent in the manufacture of glass, and important in the production of detergents and industrial chemicals. Over 95 per cent of the output is exported to markets in South East Asia, the Indian sub-continent, Africa and the Middle East.
