Emmett Hayden (fl. c. 1925 - 1960s) was a California cartographer based near Los Angeles. The founder of the Hayden Map Company, he started his map-making career mapping sub-divisions in the Los Angeles area. Then, in 1927, Hayden secured a lease from the National Park Service to build a hunting and fishing cabin in the Mammoth Lakes region. He then spent from 1927 until 1937 building his cabin from local materials entirely by hand. Hayden eventually spent most of his time at the cabin as a hunting and fishing guide and continued making maps, but in support of his new business. The Margaret and Emmett Hayden Cabin still stands today and serves as the Mammoth Lakes Museum.
