Carlo Giorgio Domenico Enrico Catani (22 April 1852 – 20 July 1918) was a civil engineer who, for the majority of his career, worked in Australia for the Victorian State Government.

He was born in Florence, Italy, and gained a civil engineering diploma at the Technical Institute there. After working in railway construction, he migrated to New Zealand in 1876, but left for Melbourne almost immediately. Within a few weeks, he joined the Victorian Department of Crown Lands and Survey as a draughtsman. In 1882, he transferred to the Public Works Department, and became head of his section in 1892.

Catani oversaw many civil engineering projects, including:

In May 1886, Catani married 26-year-old Cathrine Hanley, the daughter of a Belfast (Port Fairy) farmer. The couple had three daughters and three sons, one of whom was killed in action in World War I. He was naturalised on 15 March 1892.

The township of Catani, Victoria, Lake Catani at Mount Buffalo, and Catani Gardens in the suburb of St. Kilda, are named after him.
