On 18 February 1991 two Provisional Irish Republican Army (IRA) bombs exploded at London mainline stations, one at Victoria station and the other at Paddington station, killing one person and injuring 38 other people at Victoria station. It was the IRA's second major attack in London in February 1991 after the Downing Street mortar attack eleven days earlier which was an attempt to assassinate the British War cabinet and the British prime minister John Major. It was also the first IRA attack against a civilian target in England since the 1983 Harrods bombing, marking a strategic change in their bombing campaign in England.

Paddington, also known as London Paddington, is a London railway station and London Underground station complex, located on Praed Street in the Paddington area. The site has been the London terminus of services provided by the Great Western Railway and its successors since 1838. Much of the main line station dates from 1854 and was designed by Isambard Kingdom Brunel. As of the 2022–23 Office of Rail & Road Statistics, it is the second busiest station in the United Kingdom, after London Liverpool Street, with 59.2 million entries and exits.
