Hikmat Sulayman (1889 – 16 June 1964) (Arabic: حكمت سليمان) was prime minister of Iraq from October 30, 1936 to August 12, 1937 at the head of a Party of National Brotherhood government.

Sulayman, of Iraqi Arab, Circassian and Georgian descent, was a key figure in the early days of Iraqi independence and the effort to create a multi-ethnic state. He came to power in Bakr Sidqi's coup, the first that the country experienced. His position was confirmed by King Ghazi.

He was president of the Chamber of Deputies in 1926. Together with Sidqi, Sulayman veered away from the pan-Arab nationalism of the preceding Iraqi governments. Together with Sidqi, he forged an alliance with Turkey and settled the border dispute with Iran, two countries he regarded as potential allies in the struggle against Arab nationalist sentiment. Nevertheless, he differed with Sidqi over the emphases of the new government, preferring to address social issues in the country, while Sidqi focused on military affairs and expanding Iraq's borders.
