Arthur Schwartz (November 25, 1900 – September 3, 1984) was an American composer and film producer, widely noted for his songwriting collaborations with Howard Dietz.

He also worked on songwriting concurrently with his studies and published his first song ("Baltimore, Md., You're the Only Doctor for Me", with lyrics by Eli Dawson) by 1923.

Their first songs together were used in the Broadway revue The Little Show (April 30, 1929) and included "I Guess I'll Have to Change My Plan", which belatedly became a hit three years later when it was recorded by Rudy Vallée.

Schwartz also started contributing songs to motion pictures, beginning with "I'm Afraid of You" (lyrics by Ralph Rainger and Edward Eliscu) in Queen High (1930).

His work includes the musical Cover Girl (1944) and the Cole Porter biographical film Night and Day (1946).
