Die Hard 2 (also known by its tagline Die Harder or Die Hard 2: Die Harder) is a 1990 American action thriller film directed by Renny Harlin, written by Steven E. de Souza and Doug Richardson, co-produced by Joel Silver, and starring Bruce Willis as John McClane alongside Bonnie Bedelia, William Sadler, Art Evans, William Atherton, Franco Nero, Dennis Franz, Fred Thompson, John Amos, and Reginald VelJohnson. The second installment in the Die Hard film series, the film was released on July 4, 1990, in the United States.

As with the first film, the action in Die Hard 2 takes place on Christmas Eve. McClane is waiting for his wife to land at Washington Dulles International Airport when terrorists take over the air traffic control system. He must stop the terrorists before his wife's plane and several other incoming flights that are circling the airport run out of fuel and crash. During the night, McClane must also contend with airport police and a military commander, none of whom want his assistance.

The film was released to positive reviews, with critics praising the film's action sequences and tone while criticizing some elements of the plot. Die Hard 2 was a major box-office success, grossing $240 million and doubling the earnings of its predecessor and finishing as the year's seventh-highest-grossing film. The film was preceded by Die Hard (1988) and followed by Die Hard with a Vengeance (1995), Live Free or Die Hard (2007), and A Good Day to Die Hard (2013).
