Alexander Porfiryevich Borodin (12 November 1833 – 27 February 1887) was a Russian Romantic composer, doctor and chemist. He was a member of the group of composers called The Five (or "The Mighty Handful"), who were dedicated to producing a specifically Russian kind of art music. He is best known for his symphonies, his two string quartets, In the Steppes of Central Asia and his opera Prince Igor. Music from Prince Igor and his string quartets was later adapted for the US musical Kismet.

He was a notable advocate of women's rights and a proponent of education in Russia and was a founder of the School of Medicine for Women in St. Petersburg.
