Chagai-II is the codename assigned to the second atomic test conducted by Pakistan, carried out on 30 May 1998 in the Kharan Desert in Balochistan Province of Pakistan.Chagai-II took place two days after Pakistan's first successful test, Chagai-I, which was carried out on 28 May 1998 in the Ras Koh area in Chagai District, Balochistan, Pakistan.

The initial goals were to test the new designs of the weapon rather than studying the effects, and were different from the first tests in that they were primarily conducted by the Pakistan Atomic Energy Commission (PAEC), with the Pakistan Armed Forces engineering formations having only a supporting role.

The tests detonated implosion-type boosted-fission military-grade plutonium devices, contrary to the Chagai-I tests that were weapons-grade uranium devices. The performance of these tests made it a total of six tests performed by Pakistan in May 1998.

The Kharan Desert is a sandy and mountainous desert, with very high temperatures. The region is characterised by very low rainfall, high summer temperature, high velocity winds, poor soils, very sparse vegetation and a low diversity of plant species; its average temperature are recorded 55 °C (131 °F) in summer and 2.5 °C (36.5 °F) in winter session (sources vary).
