Hi Uncle Sam

Hi Uncle Sam! is a poem by Irish poet W. F. Marshall. It asks of Americans that they remember the input and support of immigrants from Ulster on the United States throughout the American Revolution.

The poem was published in Marshall's book, Ulster Sails West, which was published in 1911. A mural in Newtownards displays a verse of the poem. The poem was also put to music and recorded by the Ulster Scots Folk Orchestra and verse was used by the Public Record Office of Northern Ireland in their Emigration Series publication.

The "Uncle Sam" of title refers to the later personification of the United States.
