Flora Ruchat-Roncati (1937–2012) was a Swiss architect and professor. She was from Ticino, and became a pioneering figure in the Ticinese School of architecture, which was influential in the mid-1970s, mixing the sensitivity to the traditional with modernism.^[1]

She graduated from the ETH Zurich in 1954, and became the first woman professor and chair of Architecture and Design in 1985.^[1]

She was co-winner, with her assistant Renato Salvi, of a competition to design the Transjurane highway in 1988.^[2] The highway joins the Swiss and French road networks through the Jura mountains and involves many tunnels. Eleven of the tunnels are over a kilometre long.
