James Blair (c. 1788 – 9 September 1841) was a Scots-Irish owner of plantations in the West Indies. He entered Parliament as a Tory in 1818 to protect the interests of slave-owners.Blair sat in the House of Commons from 1818 to 1830, and later from 1837 to 1841. When slave-owners were compensated for the abolition of slavery in British colonies in 1833, Blair received the biggest single compensation payment.
