Portrait of a Young Woman is a painting which is commonly believed to be by the Italian Renaissance painter Sandro Botticelli, executed between 1480 and 1485. Others attribute authorship to Jacopo del Sellaio. The subject, likely Simonetta Vespucci, is shown in side profile, wearing "Nero's Seal" around her neck. It is housed in the Städel of Frankfurt, Germany. Other Botticelli portraits with the same name are housed in Uffizi, Florence, and the Staatliche Museen in Berlin.
