Harish Iyer, also known as "Aham", hiyer and "Harrish Iyer" (born 16 April 1979) is an Indian equal rights activist. Iyer engages in advocacy for a number of causes, including promoting the rights of the lesbian, gay, bisexual, and transgender (LGBT) community, children, women, animals, and survivors of child sexual abuse. Harish Iyer was also one of the most vocal proponents of the decriminalization of homosexuality in India. He has engaged in several awareness campaigns about the impact of the decision, and condemned the ruling via media advocacy. He has written articles and letters on the subject and appeared on top national television news shows to highlight the plight of the LGBT community in India in wake of the decision. He was one of the people to move the Indian Supreme Court to decriminalize homosexuality. In June 2018, he filed an Impleadement Application in the 377 case. In August 2018, the National Human Rights Commission (NHRC) appointed Iyer to the Core Group on LGBTI issues. This is the first group set up to look into concerns and challenges of the community, in a bid to harmonise existing laws with the needs of the community.
