Pat Martino (born August 25, 1944) is a jazz guitarist and composer within the post-bop, fusion, mainstream jazz and soul jazz idioms. He is noted for his mathematical approach to the instrument (he has released textbooks such as Linear Expressions) and advanced knowledge of music theory.

Martino was born Pat Azzara in South Philadelphia. He began playing professionally at the age of 15 after moving to New York City. He lived for a period with Les Paul and began playing at jazz clubs such as Smalls Paradise. He later moved into a suite in the President Hotel on 48th Street. He would play at Smalls for six months of the year, and then in the summer play at the Club Harlem in Atlantic City.
