Michielina (also known as Michaelis or Michieletta) della Pietà (fl. ca. 1700 – 1744) was an Italian composer, violinist, organist, and teacher of music. A foundling admitted in infancy to the Ospedale della Pietà in Venice, della Pietà received a thorough musical education from early childhood in the convent's coro, or music school; she became its principal organist and was active as a violinist in the orchestra. As a composer she was active during the tenures of Francesco Gasparini, Giovanni Porta, Gennaro D'Alessandro, Nicola Porpora, and Andrea Bernasconi as heads of the school; she was further licensed to teach in 1726. She is known to have composed a litany for the Feast of the Nativity in 1740, and to have written a setting of the hymn Pange lingua in 1741. Nothing further is known
