This is a list of compositions by Giovanni Pierluigi da Palestrina, sorted by genre. The volume (given in parentheses for motets) refers to the volume of the Breitkopf & Härtel complete edition in which the work can be found. Six of the volumes of masses and some of his motets and other works were published in these editions during Palestrina's lifetime. Others were collected later, from papal choirbooks and other sources. The dates of most pieces are unknown, unless they were known to have been composed in connection with some celebration. Of those works published during Palestrina's lifetime, many were composed considerably earlier than their date of publication, and of the others a large number remained unpublished until the 19th century.
