Domestic tourism is tourism involving residents of one country traveling only within that country.^[1] Such a vacation is known as a domestic vacation (British: domestic holiday or holiday at home). For large countries with limited skill in foreign languages, for example Russia, Brazil, Canada, Australia, United States, China and India, domestic tourism plays a very large role in the total tourism sector.

During the COVID-19 pandemic, domestic tourism increased significantly, as countries closed their airports to minimize the spread of COVID-19. Jobs and businesses were lost as a result of the general decline of tourism.^[2]

In British English this may also be called a staycation, a portmanteau of "stay" and "vacation", although this is not to be confused the concept of a vacation in which one stays overnight at their own home. The use of the term "staycation" to refer to a domestic holiday was popularized in the late 2000s by its use in the British media in their reporting of the increase in such tourism during the Great Recession^[3][4] when the weakness in the pound made travel abroad more expensive.
