San Giovanni in Laterano Church, Roman Catholic church in Bottonuto district, Milan, Italy

San Giovanni in Laterano was a church in Milan's Bottonuto district, at the corner of the vanished vicolo di San Giovanni in Laterano and contrada dei Tre Alberghi. Tradition dates it to the 4th century, under Bishop Mona, and by 1388 it held its own parish. It was demolished in 1936.

The church was founded in the 4th century under Bishop Mona and served as a parish church from 1388 onwards. It was demolished in 1936 during urban renovation works, with its parish functions transferred to a new church established in 1928.

The name San Giovanni Isolano has several explanations: it may come from a founder named Isolano, or from the Seveso, which ran beneath the church and turned the name into "in Laterano". A third account links it to indulgences granted by Pope Leo X, as at the Roman basilica of San Giovanni in Laterano.

Since the church was demolished in 1936, it exists today only in historical records and documentation. Visitors interested in learning about the Bottonuto neighborhood's history can consult old maps and archives to understand its former location and significance.

Pope Leo X granted this church special indulgences similar to those of the Basilica of San Giovanni in Laterano in Rome. This papal honor reflected the importance the site held within Milan's Catholic community.
