John Reily (1763–1850)[1] was a soldier in the American Revolution who later held a number of civic positions including helping draft the Ohio State Constitution.

[8][9] In 1799, he was elected clerk of the Legislature of the Northwest Territory, and re-elected to that position in 1800 and 1801.

[10] He was concurrently appointed as clerk for the supreme court of Butler County, a position which he also maintained until 1842.

[10] At first he worked from a small building outside the old fort at Hamilton, before moving the offices to his home, and in 1824 to the newly built court house.

[10] The Reilys had two daughters and three sons,[10] one of whom, Robert, founded the town of Wyoming, Ohio.
