The 1870 Barcelona yellow fever epidemic was an epidemic that took place in the Spanish city of Barcelona in 1870.
The epidemic started in August 1870 and lasted to the end of the year. The yellow fever virus is transmitted via a species of invasive mosquitoes called Aedes aegypti. The yellow fever was brought to the city by a ship that had arrived from Cuba, but the mosquitoes failed to survive Barcelona's cold weather conditions in December 1870.
