The Society for Effecting the Abolition of the Slave Trade, also known as the Society for the Abolition of the Slave Trade, and sometimes referred to as the Abolition Society or Anti-Slavery Society, was a British abolitionist group formed on 22 May 1787. 

The society was established by twelve men; including prominent campaigners Thomas Clarkson and Granville Sharp, who, as Anglicans, were able to be more influential in Parliament than the more numerous Quaker founding members. The society worked to educate the public about the abuses of the slave trade, and achieved abolition of the international slave trade when the British Parliament passed the Slave Trade Act 1807, at which time the society ceased its activities.
