Lonsdale is a neighborhood in Knoxville, Tennessee, United States, located northwest of the city's downtown area. Established in the late-19th century as a land development project, Lonsdale incorporated as a separate city in 1907, and was annexed by Knoxville in 1917. After a period of decline in the latter half of the 20th century, Lonsdale has recently undergone several major revitalization efforts.
