Barb Tarbox, MSM (April 10, 1961 – May 18, 2003) was a Canadian anti-smoking activist.

A lifelong smoker dying of lung and brain cancer, she openly discussed her illness, its cause and its consequences, which propelled her to prominence.

She wanted to be a part of the popular kids, which were smokers, leading to her taking on smoking at the age of 11.

During the last months of Tarbox's life she went around Canada teaching young adults about the consequences of smoking and how it looks to be a smoker.

On December 5, 2003, Barb Tarbox was posthumously awarded the Meritorious Service Medal[2] by Her Excellency, the Right Honourable Adrienne Clarkson, Governor General of Canada, for devotion to the anti-smoking cause.
