Walsh is an unincorporated community located in the town of Porterfield, in Marinette County, Wisconsin, United States.

[1] It is connected by road to Rubys Corner to the east, Loomis to the west, and Porterfield to the south (via County Trunk Highway E).

[4][5][6] It was named for the family of Jacob Rawn (1819–1896; surname earlier spelled Rein, Raan, or Rhyne),[7] who settled in the area.

Walsh was the founder of the Chicago National Bank, and he purchased a controlling interest in the Wisconsin & Michigan Railway in October 1900.

Gravel from the pit was delivered to Iron Mountain and then used to build the Ford Motor Company factory in nearby Kingsford.
