World No Tobacco Day is celebrated around the world every year on May 31.

This yearly celebration informs the public on the dangers of using tobacco, the business practices of tobacco companies, what WHO is doing to fight the tobacco epidemic, and what people around the world can do to claim their right to health and healthy living and to protect future generations.

The Member States of the World Health Organization created World No Tobacco Day in 1987 to draw global attention to the tobacco epidemic and the preventable death and disease it causes. In 1987, the World Health Assembly passed Resolution WHA40.38, calling for 7 April 1988 to be an "a world no-smoking day." In 1988, Resolution WHA42.19 was passed, calling for the celebration of World No Tobacco Day, every year on 31 May.
