Luigi Molinari (1866–1918) was an Italian anarchist, journalist, and lawyer known for publishing the libertarian periodical L’Università popolare and for his support for Ferrer Modern Schools in Italy.

After high school, Molinari studied law in Pisa, where he read Pietro Gori's Pensieri ribelli ("Rebel thoughts") and developed an affiliation with anarchism.

The same year, Molinari led the internationalist newspaper La Favilla, which had been founded by Paride Suzzara Verdi to support the creation of local worker social cooperatives.

Molinari was ejected from the 1893 Zürich Socialist Congress and arrested for his role in talks preceding insurrection in Lunigiana, for which he was sentenced before military tribunal to 23 years of prison.

He advocated for broader education, including instruction on scientific thought, and civic consciousness as a better solution for crime than punitive criminal law.

Together they raised sufficient funds to open a modern school in Milan's Lambrate suburb, but it was shortly closed with the start of World War I.
