Leader is a populated place in Adams County, Colorado, in the United States.

[3] A chapter of the Colorado Grange was organized in Leader in 1916, founded by area resident J. F. Girardot.

[4] In the early years, Leader was noted for its prairie dogs and ground squirrels; the latter were said to be highly destructive to corn, peanut, and bean crops in Leader.

Drilling commenced at the 2,000 acres (810 ha) Burkhart Ranch in 1954.

[13] The Leader School, a one-room schoolhouse, operated until 1956, when Adams County's schools were consolidated; students were afterwards bused to Byers, 12 miles to the south in Arapahoe County.
