Lyon Township was founded on March 7, 1834 as a general law township. The Township Board of Trustees approved a resolution on January 15, 1979 making Lyon Township a charter township. The seven member Board of Trustees, consisting of a supervisor, clerk, treasurer and four trustees, directs the township.

The Township is located in the southwest corner of Oakland County, which is in southeast Michigan. Approximately 32 square miles in size, the Township is bordered by Dixboro Road on the west, Napier Road to the east, Pontiac Trail to the north and Eight Mile Road to the south. Neighboring communities are the cities of South Lyon (which is partially surrounded by the Township), Novi and Wixom, and the townships of Milford, Green Oak and Salem.
I-96 bisects the northern portion of the Township, paralleling Grand River Avenue.

The population of Lyon Township in the 2000 Census was 11,041, an increase of 1,591 over 1990. Population growth is expected to continue to increase as new residential developments come into the township.

Two school districts serve the Township - South Lyon Community Schools and Northville Community Schools. We are served by 5 post offices (New Hudson, South Lyon, Northville, Wixom and Milford).
