Giovanni Battista Bassani (c. 1650 – 1 October 1716) was an Italian composer, violinist, and organist.
Charles Burney and John Hawkins claimed he taught Arcangelo Corelli, but there is no solid evidence for this assertion.
He was maestro di cappella at Duke Alessandro II della Mirandola's court in 1680, and was elected principe at the Accademica Filarmonica in Bologna.
He became director of music at Santa Maria Maggiore in Bergamo in 1712, and also taught at the Congregazione di Carità in the same city until his death.
He wrote 13 oratorios, but only four survive, and all 13 of his operas have been lost aside from a few arias from Gli amori alla moda.
