The 2005 Amman bombings were a series of coordinated suicide bomb attacks on three hotel lobbies in Amman, Jordan, on 9 November 2005. The explosions at the Grand Hyatt Hotel, the Radisson SAS Hotel, and the Days Inn started at around 20:50 local time (18:50 UTC) at the Grand Hyatt. The three hotels are frequented by foreign diplomats. The bomb at the Radisson SAS exploded in the Philadelphia Ballroom, where a Jordanian wedding hosting hundreds of guests was taking place. The attacks killed 57 people and injured 115 others.

Al-Qaeda in Iraq was quick to claim the attack. The bombings, a rare terror attack in Jordan, then spurred a wave of new anti-terror measures by the Jordanian government.
