Somappa Rayappa Bommai (6 June 1924 – 10 October 2007) was an Indian Politician who was the 4th Chief Minister of Karnataka.

[6] S. R. Bommai was born on 6 June 1924 in a Sadar Lingayat family at Karadagi village of Shiggaon taluk of the then undivided Dharwad District.

He along with Ramakrishna Hegde, J. H. Patel and H. D. Deve Gowda was instrumental in the Janata Party forming a government in Karnataka for the first time in 1983.

After Hegde quit on moral grounds, Bommai took charge as Chief Minister on 13 August 1988 and his government was dismissed by the then Governor, P. Venkatasubbaiah, on 21 April 1989 on the grounds that his government had lost its majority following large-scale defections engineered by several Janata Party leaders.

The apex court spelt out restrictions on the centre's power to dismiss a state government under Article 356.
