Blackpool Illuminations is an annual lights festival, founded in 1879 and first switched on 18 September that year, held each autumn in the British seaside resort of Blackpool on the Fylde Coast in Lancashire.

Also known locally as The Lights or The Illuminations, they run each year for 66 days, from late August until early November at a time when most other English seaside resorts' seasons are coming to an end. They are 6.2 miles (10 km) long and use over one million bulbs. The display stretches along the Promenade from Starr Gate at the south end of the town to Bispham in the north.
