Wilton Rancheria is a federally recognized Native American tribe of Miwok people based in northern California.

[3] The rancheria (or reservation) consists of 38.5 acres (156,000 m2) of land[4] located in the Sacramento Valley, near the city of Elk Grove in the community of Wilton.

The Legislative Branch is responsible for making laws and regulations, authorizing expenditures, and promoting social advancement of the tribe as a whole.

The Judicial Branch acts as the tribe's Tribal Court, which is responsible for jurisdiction over all criminal and civil cases.

The tribal members are descendants of the Plains and Sierra Miwok, who lived and prospered in the Sacramento Valley long before encountering European explorers and colonists.

[3] In the 1970s, the policy of termination was reconsidered by President Richard M. Nixon and Congress, which began to favor Indian self-determination.

In part this was due to widespread Native American activism stressing their assertion of sovereignty and seeking more control over their affairs.

176, Notices 55731, states that the Tribe had designated boundaries of the Service Delivery Area (SDA) of Sacramento County, California.

It plans to develop the Wilton Rancheria Elk Grove Resort and Casino on this land, to generate revenue for tribal welfare and education,[5] and won a ruling in its favor by the courts to enable it to do so.
