The 1997 Grand National (known officially as the Martell Grand National and also informally as the Monday National) was the 150th official running of the Grand National steeplechase held at Aintree near Liverpool. The race was scheduled to be run on Saturday 5 April 1997, but was postponed by two days to Monday 7 April after a Provisional Irish Republican Army (IRA) bomb threat forced the evacuation of the course.
