Ivan Toms (11 July 1952 – 25 March 2008) was a South African physician, who battled the Apartheid era government as a prominent anti-Apartheid and anti-conscription activist.  At the time of his death in 2008, Toms was serving as the Director of Health for the city of Cape Town, South Africa. 
Toms was drafted into the national service in the South African Defence Force (SADF), as a non-combatant doctor in 1978. He opposed the goals of the SADF, but refused to leave South Africa. He spent much of his six months as a doctor in Namibia, which was then known as South West Africa and was controlled by South Africa.
Once he returned to Cape Town, Toms set up a medical clinic in the squatter settlement of Crossroads, which is located about 15 km outside of the city in the Cape Flats area. He was the only doctor who served the Crossroads' population of approximately 60,000 people. In September 1983, Toms witnessed a three-week-long confrontation between the Crossroads community and the South African police and security forces, who were trying to tear down "illegal" buildings in the settlement. After witnessing the violence and brutality of the raid, Toms vowed never to serve in the SADF again, even in a non-combatant capacity. He went public with his opinions on what he had witnessed and became a founding member of the End Conscription Campaign (ECC) in 1983. Toms' co-founders of the ECC included other prominent anti-conscription activists including Nan Cross.
Toms went on a three-week-long hunger strike in February 1985 to protest the government's decision to buldoze the Crossroads shanty town. The destruction of Crossroads resulted in violence and the deaths of several people as residents tried to resist the destruction. Toms commented during his hunger strike that, "As a Christian, I am obliged to say no, to say never again will I put on that SADF uniform."
The SADF officially took control of Toms' health clinic in 1986. The following year, in July 1987, Toms defied the SADF when he was called up for one month of compulsory service.  He was sentenced to 21 months in prison in 1988 for defying the order and ultimately served nine months in Pollsmoor Prison.
Ivan Toms became the national co-ordinator of the National Progressive Primary Healthcare Network in 1991 at the end of the Apartheid era. The AIDS virus was beginning to sweep through South Africa at the time. Toms, as the national co-ordinator, began to implement a series of programs to combat the spread of AIDS and HIV in the country. He was considered a pioneer in the advocacy of the use of antiretroviral drugs to fight the disease. He became director of the Students' Health and Welfare Centres Organisation in 1993, which is a non-governmental organization which runs medical clinics staffed by students in poor areas. He continued to work for non-governmental charities until 1996, when he became the Health Director in the City of Cape Town. His name is remembered in the Ivan Toms Centre for Men's Health (Cape Town) in Woodstock, Cape Town, which works in the prevention, diagnosis, and treatment of sexually transmitted infections.
Ivan Toms died unexpectedly of meningitis at his home in Mowbray on 25 March 2008, at the age of 54.  He was honored by prominent South African political figures, including Archbishop Emeritus Desmond Tutu and the Mayor of Cape Town, Helen Zille. Archbishop Tutu described himself as "devastated" by the news of Toms' death and paid tribute to him saying, "I thank God that I knew him. Knowing him makes (one) feel proud. This is a prime example of someone who had ubuntu. He was utterly selfless." His funeral, which was attended by hundreds of people including Archbishop Tutu, was held at St. George's Cathedral in Cape Town.
