County of Yarmouth was a full-rigged ship built in Belliveau's Cove, Nova Scotia in 1884.

The ship was one of a series of very large wooden ships proudly named after major shipbuilding counties of Nova Scotia at the end of the Age of Sail.

The ship enjoyed a profitable decade of service circling the globe several times but most often trading between South American, Canadian and British ports.

She survived a serious grounding at Low Point, Cape Breton in 1893.

After being dismasted in December 1895, she was to be broken up at Grimsby, England but was purchased by the government of Argentina as a school ship.
