Neggio is first mentioned in 807 as
Nego. In 1335, it was mentioned as
Negio. Tombs from the 3rd to 4th centuries suggest that there was a
Roman settlement near the modern village. In the 15th century it was mentioned as a separate
Vicinanza. In 1611, it split from the
parish of
Agno. Since 1938, there has been a small community of
Dominican nuns. In January 1944, they housed
Edda Ciano, the daughter of
Benito Mussolini, along with her children. The church of S. Maria dell'Annunciata has
frescoes from the 14th century, which date from the previous building that was demolished in 1620. Nothing remains of the church of San Giorgio, but a chapel was built on the same hill in the 18th century.

At the beginning of the 21st century, most of the workers worked outside the municipality in
Lugano and the
Vedeggio plain. In 1956 vocational and home economics courses were introduced in the municipality. The school house, a gift from the Soldati family, has included a handicapped workshop since 1986. ==Geography==
