Charles Thomas de Lorraine (7 March 1670 – 12 May 1704), prince de Vaudémont, was a field marshal in the Austrian army.

His father used the style of prince de Vaudémont, although he held no corresponding territory, until 1708 when he received the allodial territory of Commercy from Leopold, Duke of Lorraine.

Like his forefathers he served in the Habsburg army against France.

He fought in Italy during the War of Spanish Succession under command of Prince Eugene of Savoy.

He was fatally wounded in a minor battle on 8 May 1704 near Ostiglia, and died 4 days later.
