Kellerman Log Cabin is a historic home located at Conesus in Livingston County, New York. It is a one-story, 20 foot by 24 foot building with a large partially exposed fieldstone chimney. It is constructed of stacked adzed logs with dovetail corner joints and mud chinking. It was built in 1816 by Isaac Kellerman. It is a rare settlement era log cabin, and one of five surviving log cabins in the upper Genesee Valley. In 1978, it was moved from its original site to a public park and now houses Ganeasos History Keepers, a local history organization.
It was listed on the National Register of Historic Places in 2007.
