Felix Viole (1856-1924) was a French-born early civil engineer, surveyor, and cartographer of Los Angeles, California. Viole moved to Los Angeles in 1888 and was the editor of the French newspaper Le Progres. He incorporated the Felix Viole Map and Address Company in 1905, which produced most of the maps of the Los Angeles area during the 1900s and 1910s, including the official maps of Los Angeles city, County, and Southern California. He was active in city politics, a Democrat, and he ran for the office of county surveyor in 1910. He married his wife, Hortense (Deleval) Viole, in San Diego in 1890 and had two children, Marie and Laurence.
