Daniel Rogers Pinkham Jr. (b. Lynn, June 5, 1923; d. Natick, December 18, 2006) was an American composer, organist, and harpsichordist

Born in Lynn, Massachusetts, into a prominent family engaged in the manufacture of patent medicines (his great-grandmother was Lydia E. Pinkham), he studied organ performance and music theory at Phillips Academy with Carl F. Pfatteicher. At Harvard University, he studied with Walter Piston; Aaron Copland, Archibald T. Davison, and A. Tillman Merritt were also among his teachers. There he completed a bachelor's degree in 1942 and a master's in 1944. He also studied harpsichord with Putnam Aldrich and Wanda Landowska, and organ with E. Power Biggs. At Tanglewood, he studied composition with Samuel Barber and Arthur Honegger, and subsequently with Nadia Boulanger.

Pinkham taught at the Boston Conservatory beginning in 1946, and at the New England Conservatory of Music from 1959 until his death in 2006; while there, he created and chaired the program on early music performance. He also at Simmons University (1953–1954), Boston University (1953–1954), and Harvard University (1957–1958). Among Pinkham's notable students were the jazz musician and composer Gigi Gryce (1925–1983) and the composer Mark DeVoto. From 1958 to 2000, Pinkham was the organist of King's Chapel in Boston, a position which gave him much exposure to and opportunity to write church-related music; the Sunday evening concert series he created there celebrated its 50th anniversary in 2007. He was also a frequent guest on the E. Power Biggs program on the CBS Radio Network. He performed regularly with the Boston Symphony Orchestra as an organist and as a harpsichordist, and he performed extensively with noted violinist Robert Brink, with whom he commissioned a duo for violin and harpsichord from Alan Hovhaness.
