The Siddis of Karnataka () (also spelled "Siddhis") are an ethnic group of mainly Bantu descent that has made Karnataka their home for the last 400 years. There is a 50,000 strong Siddhi population across India, of which more than a third live in Karnataka. In Karnataka, they are concentrated around Yellapur, Haliyal, Ankola, Joida, Mundgod and Sirsi taluks of Uttara Kannada and in Khanapur of Belgaum and Kalghatgi of Dharwad district. Many members of the Siddis community of Karnataka had migrated to Pakistan after independence and have settled in Karachi, Sindh. The majority of the Siddhis in Karnataka are descendants of Siddhi slaves who were brought from East Africa (mostly Mozambique) and Ethiopia to Goa by the Portuguese, British and the Arabs between the 16th and 19th centuries. During the Goan Inquisition, some of these slaves were freed and some escaped into the forests of the neighbouring Karnataka state. It has been reported that these Siddis believe that Barack Obama shares their genepool and that they wanted to gift a bottle of honey to him on his visit to India in 2010.<ref name="http://www.openthemagazine.com">Anil Budur Lulla, " A Bottle of Honey for Our Brother Prez", Short Takes section, Open Magazine, October 30, 2010</ref>
