This is a list of 21st-century classical composers, sortable by name, year of birth and year of death.

The list includes composers who have made classical music since 2001. The 21st century is defined by the calendar rather than by any unifying characteristics of musical style or attitude, and is therefore not an era of the same order as the classical or romantic. However, the century to date can be considered a continuation of the postmodern era that began during the 20th century and differs from the earlier modernist era in matters of attitude more than style.
