Tine van der Maas (born 15 March 1954) is an Argentine-born South African nutritionist and HIV/AIDS denialist.
She was the caretaker of Nozipho Bhengu, who died in 2006 from an AIDS-related illness after being persuaded to stop taking her medication.
Former South African president Thabo Mbeki questioned the link between HIV and AIDS.
In his speech to the 13th International AIDS Conference in Durban (2000), he stated, "The world's biggest killer and the greatest cause of ill health and suffering across the globe, including South Africa, is extreme poverty."
This occurred at the same time Tine van der Maas came to public attention working with then Minister of Health, Dr. Manto Tshabalala-Msimang.
