A ledger stone or ledgerstone is an inscribed stone slab usually laid into the floor of a church to commemorate or mark the place of the burial of an important deceased person. The term "ledger" derives from the Middle English words lygger, ligger or leger, themselves derived from the root of the Old English verb liċġan, meaning to lie (down). Ledger stones may also be found as slabs forming the tops of tomb chest monuments.
