Luigi Rosselli is an Italian born architect who practices in Australia. He was born in Milan in 1957. He studied architecture at the Ecole Politechnique Federale in Lausanne, where he met Alvaro Siza and Mario Botta, who offered Rosselli a job in 1979. He left the next year to work for Mitchell/Giurgola in their New York office. That firm won a commission to design the Australian Parliament House, and Rosselli moved to Canberra in 1981 to work on that project. He met his wife there, and the two of them moved to Sydney in 1984. He joined Furio Valich's firm, then opened his practice a year later.
His work has primarily been residential, but in the 1990s he worked on a series of restaurants.
He says that his approach to architecture is "humanist, where people and environment take precedence over preconceived design dogmas" 
In 2004, a house he designed in Mosman won a commendation from the Royal Australian Institute of Architects (AIA), and in 2006, he shared the AIA's NSW Wilkinson residential award for a farmhouse in Mount Minderoo, near Mittagong.
