Ludovico Tommasi (Livorno, 1866 - Florence 1941) was an Italian painter.
Inspired by the example of his elder brother Angiolo and his cousin Adolfo, Ludovico Tommasi devoted himself to painting, developing his art in close contact with Silvestro Lega, a frequent visitor to the Tommasi family villa at Bellariva. He made his debut at the Florence Promotrice in 1884 with a life study.
After his military service in Milan between 1888-1891, Tommasi and his brother Angiolo frequented the cultural circle that gravitated around Giacomo Puccini at Torre del Lago, and it was here that he came into contact with several exponents of the Tuscan artistic avant-garde, including Galileo Chini and Oscar Ghiglia.
