Marie Leszczynska (pronounced [maʁi lɛɡzɛ̃ska]), was a Polish noblewoman and French Queen consort.
The daughter of King Stanislaw Leszczynski — Stanislaw I of Poland (later Duke of Lorraine)– she married King Louis XV of France and became queen consort of France.
She served in that role for 42 years from 1725 until her death in 1768, the longest service of any queen of France, and was popular due to her generosity and piety.
She was the grandmother of Louis XVI, Louis XVIII, and Charles X of France.
