The Panama is a breed of domestic sheep native to the United States.
[2] Today Panama sheep are rare - largely unknown outside Idaho and Montana, and are one of only a few breeds which were started by private individuals in the United States.
[3] They were developed by James Laidlaw, a Scottish immigrant to the region who was seeking a large sheep better suited to the range than the Merinos which were most common in the late 19th and early 20th centuries.
[4] Panamas are polled sheep with white fleece of medium length and a large body suitable for meat production.
[6] A breed registry was formed in 1951, but it has been inactive and it's unclear whether the majority of Panamas present today have not been crossbred.
