巴拿马羊（Panama），是一种原产于美国的绵羊，原产于爱达荷州，目前也仅多见于爱达荷和蒙大拿州，也是美国少数由私人培育出来的绵羊品种。虽然有着巴拿马的名字，事实上这种羊是以巴拿马-太平洋国际博览会命名的。

此种是在19世纪末、20世纪初由苏格兰裔的詹姆斯·赖罗，以朗布伊埃公羊和林肯母羊杂交而成，以繁殖比美利奴羊更能适应山区环境的大型绵羊。

本种无角，长有中等长度的白毛，体型较大，适合肉用。非常适合洛矶山地区北部的恶劣环境。其品种登记于1951年获批，但并不活跃，亦未知有无大规模杂交情况出现。目前唯一已知的纯种群体存活于爱达荷大学。

The Panama is a breed of domestic sheep native to the United States. Though its name is identical to the country of Panama, the breed was in fact named for the Panama-Pacific International Exposition where it was shown early on in its history.

Panama sheep originated in 1912 in Muldoon, Idaho. 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. 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. The foundation of the breed was a cross of Rambouillet rams to Lincoln ewes.
