Seboeis is a plantation in Penobscot County, organized on March 31, 1890 from township T3 R8 NWP. Its organization was confirmed by the legislature in 1895.
The name, meaning little brook, may have its origins in a description of a portion of Seboeis Stream that begins its journey out of Endless Lake much smaller than it is when it exits the plantation several miles to the south.
Other than South Branch Lake on its eastern boundary, and the Canadian Atlantic Railway line in the south, the area has few outstanding physical features.
