Greg Anderson (born September 28, 1981) is an American pianist, composer, video producer, and writer. According to his website, Anderson's mission is to "make classical piano music a relevant and powerful force in society."

Born in St. Paul, Minnesota, Anderson began his piano studies at age seven with Kim Craig, with whom he studied for eleven years, at the Saint Paul Conservatory of Music. He attended the Aspen Music Festival, the Bowdoin International Music Festival, Pianofest in the Hamptons, and the Banff Keyboard Festival.

Anderson studied with Julian Martin at The Juilliard School where he received his Bachelor and Master of Music degrees in Piano Performance in 2004 and 2006. In 2003, Anderson won the Juilliard Concerto Competition, playing Beethoven’s 4th Piano Concerto with the Juilliard Orchestra. He was awarded a scholarship from the Jack Kent Cooke Foundation in 2004. He then studied with Peter Frankl at the Yale School of Music, where he received his Master of Musical Arts (2008) and Doctorate of Musical Arts (2013). Aside from his work in academic settings, Anderson also has a long history of studying with distinguished pianist and pedagogue Aiko Onishi.

As a Steinway Artist, Anderson performs around the world and has released two solo albums.

In addition to playing solo performances, Anderson concertizes with his piano duo partner, fellow Steinway Artist Elizabeth Joy Roe. The duo's partnership has been characterized as "the intense synchronization of genius" and "the most dynamic duo of this generation." In the book "Driven: Six Incredible Musical Journeys" Nick Romeo writes, "[Anderson & Roe] hook listeners by putting into practice an expanded concept of what classical music can be: sexy, funny, personal, and interactive." Adrian Daub's book "Four-Handed Monsters" calls Anderson & Roe "one of the most successful piano duos active in the United States," citing the duo's "innovative, frequently pop-inflected repertoire (a few years ago they premiered a four-hand transcription of the Star Wars soundtrack), and their ironic emphasis of the eroticism of four-hand performance."

They are widely known for their daring four-hand piano technique, as described by the Southampton Press: "Their hand movements and the intertwining of arms, and it seemed at times of fingers, was elaborately and brilliantly choreographed. There were times when their hands seemed magically to occupy the same space, though they were playing different notes. The entire process was a small ballet of the hands, as wonderful to watch as to hear."

Their albums on the Steinway Label (When Words Fade, An Amadeus Affair, and The Art of Bach) have spent dozens of weeks at the top of the Billboard Classical Charts.

Anderson & Roe served as webcast hosts for the inaugural Cliburn International Junior Piano Competition and Festival in 2015. They provided competitor information and Competition commentary, and conducted interviews to provide behind-the-scenes insight. Anderson & Roe then served as hosts of the 15th Van Cliburn International Piano Competition and #Cliburn2017 Webcast in 2017.
