Tommaso Bernardo Gaffi (* about 1665 in Rome; † February 11, 1744 ebenda) was an Italian organist, kapellmeister and composer.
Gaffi was a pupil of Bernardo Pasquini and then worked at various churches as organist and kapellmeister.
He created oratorios, six of which have been preserved as well as several secular cantatas. The influence of the galant style that was also emerging in Rome at that time can be seen in his work.
