Larry Fine (October 5, 1902 – January 24, 1975) was an American comedian and actor, who is best-known as a member of the comedy act The Three Stooges.

Fine was born to a Jewish family as Louis Feinberg in Philadelphia, Pennsylvania, at the corner of 3rd and South Streets. The building there is now a restaurant which is called Jon's Bar & Grill - "the birth place of Larry Fine", but is not actually where he was born. The upstairs houses a small Stooge museum. His father, Joseph Feinberg, and mother, Fanny Lieberman, owned a watch repair and jewelry shop. When Larry was a child he burned his arm with some acid that his father used to test whether or not gold was real. Mistaking it for a cool drink Larry had the bottle to his lips when his father noticed and slapped it from his hand, splashing his forearm with acid. Later Larry received violin training to help strengthen his damaged muscles and this talent would be observed in many of the Stooges' films. He became quite proficient on the instrument, and his parents wanted to send him to a European music conservatory, but the outbreak of World War I prevented him from going. In scenes where all three are playing fiddles, only Larry is actually playing his instrument; the others are pantomiming. To further strengthen his arm, Larry took up boxing as a teenager. He fought and won one professional bout. His career as a pugilist was stopped by his father, who was opposed to Larry's fighting in public.

As Larry Fine, he first performed as a violinist in vaudeville at an early age. In 1925, he met Moe Howard and Ted Healy. Howard and his brother Shemp had been working as audience stooges for Healy. Shemp left soon after to attempt a solo career and was in turn replaced by another brother, Curly. Larry's trademark bushy hair came out, according to rumor, from his first meeting with Healy, in which he had just wet his hair in a basin, and as they talked, it dried oddly. Healy told him to keep the zany hairstyle and, according to a 1973 radio interview with Moe:
