Thomas Daniel (16 September 1762 – 6 April 1854) was a slave owner and sugar merchant in Bristol who was known as the "King of Bristol" because of his omnipotence in corporate affairs for over 50 years. Across the Americas he owned plantations worked by enslaved Africans and people of African descent. He was a partner in Bristol businesses and owned ships linked directly to the slave economy. For decades he was a key member of organisations in Bristol such as the Society of Merchant Venturers and the West India Association which lobbied against the abolition of slavery.
