Ena Cazzulani Allegri, born Elena Cazzulani (1920 – 2008) was an Italian writer and poet. In the 1980s, she founded at her home a literary salon, which became an essential meeting place for the Lodi's intellectuals.
Elena Cazzulani is born in 1920 in Lodi, and she is the daughter of Giovanni Cazzulani, architect and the last headmaster of the Collegio Cazzulani School, founded by her grandparents, Francesco Cazzulani and Elena Roda. Unlike her closest ancestors, Ena held no administrative position at the school, preferring to dedicate herself to writing. She counted her family history in the book Il collegio Cazzulani (The Cazzulani School) in 1988.
She has written poems, novels, and biographies dedicated to several important women in the region, including Ada Negri, Vittoria Manzoni, Cristina Trivulzio Belgiojoso, Maria Cosway, Carlotta Ferrari, and Giuseppina Strepponi.
The municipality of Lodi dedicated a street to her in December 2014. One of the exterior walls of the Francesco Cazzulani Institute bears her portrait reproduced on a monochrome turquoise ceramic tile, work by Luigi Poletti. Elena Cazzulani died in Lodi in 2007 at the age of 87.
