Johnston Hastings "Jack" Skelly Jr. (1841–1863) was a Union soldier — a corporal in the 87th Pennsylvania Infantry — who died as a result of wounds sustained at the Second Battle of Winchester. He was the friend, and possibly fiancé, of Jennie Wade, the only civilian to die in the Battle of Gettysburg. He was buried in Evergreen Cemetery in Gettysburg, Pennsylvania, near Wade's grave.
