Anti Whaling Society (AWS) is a non-profit, non-governmental organization dedicated to the end of whaling everywhere on Planet Earth.

AWS got its name from the Anti Slavery Society founded in 1823 by William Wilberforce and Thomas Clarkson to fight for the abolition of slavery in the British Empire which was achieved ten years later by the Slavery Abolition Act of 1833. A successor organization was formed in 1839 to fight for global abolition. Today it has become Anti-Slavery International.

AWS sees its mission as the abolition of whaling instead of slavery, with the difference that slavery put free people in chains, while whaling kills them.

As one of its arguments against whaling, AWS points at the majority opinion of the scientific community in regard to the extraordinary complexity of the brains and of the behavior of many cetacean species.
