Lewis and Clark County

Lewis and Clark County is an administrative division in Montana encompassing a mix of settled communities and open land across rolling terrain. The region includes the state capital Helena along with smaller towns and rural areas.

The territory was originally established in 1865 as Edgerton County and renamed in 1868 to honor the exploration journey of Meriwether Lewis and William Clark. The name change reflected the region's connection to this important expedition.

The county maintains multiple educational institutions, public libraries, and community centers that serve its population of over 70,000 residents through various programs.

The administrative center in Helena offers services such as vehicle registration, property tax matters, and public facilities for visitors and residents. Most government services are concentrated in the county seat.

All license plates issued here display the number 5, immediately identifying vehicles registered in this county. This marking system makes them instantly recognizable among other Montana vehicles.
