Thillaiaadi Valliammai (22 February 1898 - 22 February 1914) was a South African Tamil woman who worked with Mahatma Gandhi in his early years when he toned his nonviolent methods in South Africa fighting its apartheid regime. Valliammai joined Gandhi's movement at the age of 16 and died soon thereafter during the anti-apartheid agitation. Gandhi later said that it was her sacrifice that increased his resolve to fight for Indian independence. In 1913, Valliammai took part in Gandhi's fight for abolition of the Indian Poll Tax. Although she was imprisoned by the British colonial government and later allowed to be released due to her illness, Vallimmai refused to do so until after the abolition of the Tax in 1914.
