Don Pedro Gómez Labrador, Marquis of Labrador (1755—1852) was a Spanish diplomat and nobleman who served as Spain's representative at the Congress of Vienna (1814–1815). Labrador did not successfully advance his country's diplomatic goals at the conference. These goals included restoring the Bourbons (who had been deposed by Napoleon) to the thrones of Spain's old Italian possessions, and reestablishing control over Spanish South American colonies, which had risen in revolt during the Napoleonic invasion of Spain.
