Rosalie is a village in Thurston County, Nebraska, United States, within the boundaries of the Omaha Indian Reservation. The population was 159 at the 2020 census.

Rosalie was platted in 1906 when the Chicago, Burlington & Quincy Railroad was extended to that point.

Rosalie was named for Rosalie La Flesche Farley, a daughter of Joseph La Flesche, the last principal chief of the Omaha tribe selected by traditional means in the nineteenth century, and the only chief of part-European ancestry. After the tribe moved onto the reservation, Rosalie La Flesche became its financial manager, managing grazing leases and other transactions. She married Edward Farley of Bancroft, Nebraska. One of her sisters was the author and activist Susette "Bright Eyes" LaFlesche, who married journalist Thomas Tibbles. Another sister was Susan LaFlesche Picotte, a physician who married a Yankton Sioux man.
