Mother Teresa (Albanian: Agnes Gonxha Bojaxhiu, Macedonian: ????? ????? ???????, Latinic: Agnes Gondža Bojadžiu; IPA: ['agn?s 'g?nd?a b?'jad?u]) (August 26, 1910 – September 5, 1997) was an Albanian Roman Catholic nun who founded the Missionaries of Charity in Kolkata (Calcutta), India in 1950. For over forty years she ministered to the poor, sick, orphaned, and dying, while guiding the Missionaries of Charity's expansion, first throughout India and then in other countries.

By the 1970s she had become internationally famed as a humanitarian and advocate for the poor and helpless, due in part to a documentary, and book, Something Beautiful for God by Malcolm Muggeridge. She won the Nobel Peace Prize in 1979 for her humanitarian work. Mother Teresa's Missionaries of Charity continued to expand, and at the time of her death it was operating 610 missions in 123 countries, including hospices and homes for people with HIV/AIDS, leprosy and tuberculosis, soup kitchens, children's and family counseling programs, orphanages, and schools.

Following her death she was beatified by Pope John Paul II and given the title Blessed Teresa of Calcutta.[
