The Choral Public Domain Library (CPDL), also known as the ChoralWiki, is an online database for choral and vocal music. Its contents primarily include sheet music in the public domain or otherwise freely available for printing and performing (such as via permission from the copyright holder).

It is a 501(c)(3), tax-deductible organization,^[1] whose contents are published under a specific copyright license, and editing articles can be allowed only for registered contributors. The CPDL stands with Musopen and the Wind Repertory Project as among the most prominent online music repertoire databases.^[2]
