Alan Curtis (November 17, 1934 – July 15, 2015) was an American harpsichordist, musicologist, and conductor of baroque opera. Born in Mason, Michigan, Curtis graduated from studies at the University of Illinois, and received his PhD in 1960 with a dissertation on the keyboard music of Sweelinck. He then relocated to Amsterdam to work with Gustav Leonhardt, with whom he subsequently recorded a number of Bach's concerti for harpsichord. In the 1960s and 1970s, he made a number of recordings of solo harpsichord music including albums dedicated to the keyboard music of Rameau and the works of Johann Sebastian Bach, such as his recording of the Goldberg Variations made on a 1728 Christian Zell harpsichord.
