Don't Lose Your Head is a 1967 British swashbuckling comedy film, the 13th in the series of 31 Carry On films (1958–1992). It features regular team members Sid James, Kenneth Williams, Jim Dale, Charles Hawtrey, and Joan Sims. Set in France and England in 1789 during the French Revolution, it is a parody of Baroness Orczy's The Scarlet Pimpernel.

The first Carry On to be produced by the Rank Organisation, Don't Lose Your Head was not conceived as a part of the series and was first released without the Carry On prefix. However, the ongoing popularity of the series persuaded Rank to add the prefix to the titles of this and the following film, Follow That Camel, when they were re-released.

French actress Dany Robin makes here her only Carry On appearance.

The film was followed by Carry On Follow That Camel (1967).
