Lander is a city in, and the county seat of, Fremont County, Wyoming, United States. Named for transcontinental explorer Frederick W. Lander, Lander is located in central Wyoming, along the Middle Fork of the Popo Agie River. A tourism center with several dude ranches nearby, Lander is located just south of the Wind River Indian Reservation. The population was 6,867 at the 2000 census.
Since 1998, Lander and Fremont County have been represented in the Wyoming State Senate by economist Cale Case (Republican).
Lander was known as Pushroot, Fort Brown, and Fort Auger prior to its current name. On October 1, 1906, Lander became the westward terminus of the "Cowboy Line" of the Chicago and North Western Railway, thus originating the slogan "where rails end and trails begin." Originally intended to be a transcontinental mainline to Coos Bay, Oregon or Eureka, California, the line never went further west, and service to Lander was abandoned in 1972. Lander is also home to the world's first professional rodeo, which continues to this day in coordination with the town's raucous Fourth Of July festivities.
