特强气旋风暴纳尔吉斯（英语：Very Severe Tropical Storm Nargis，联合台风警报中心编号：01B，中国大陆定为超级气旋风暴）是2008年北印度洋气旋季第一个获得命名的热带气旋，也是自2006年的气旋马拉以来第一个登陆缅甸的风暴。纳尔吉斯横扫了缅甸南部的海岸线，引起严重风暴潮，造成极大破坏，它在该国至少导致90,000人死亡，56,000人失踪。它是缅甸历史上最严重的自然灾害，CNN引用美国官方估计最后的死亡人数将超过十万人。

纳尔吉斯于4月27日在孟加拉湾中部形成，起初缓慢向西北移动，受惠于良好环境得以快速增强。4月29日系统受干空气影响强度减弱，在开始转向东移后重新快速增强，并于5月2日达到强度的颠峰（至少为165公里每小时）。不久风暴在缅甸伊洛瓦底省登陆，进一步移入内陆后在缅甸与泰国的边境附近消散。

Cyclone Nargis caused the worst natural disaster in the recorded history of Myanmar during early May 2008. The cyclone made landfall in Myanmar on Friday, 2 May 2008, sending a storm surge 40 kilometres up the densely populated Irrawaddy delta, causing catastrophic destruction and at least 138,000 fatalities. The Labutta Township alone was reported to have 80,000 dead, with about 10,000 more deaths in Bogale. There were around 55,000 people missing and many other deaths were found in other towns and areas, although the Myanmar government's official death toll may have been under-reported, and there have been allegations that government officials stopped updating the death toll after 138,000 to minimize political fallout. The feared 'second wave' of fatalities from disease and lack of relief efforts never materialized. Damage was estimated at over K62,988,000,000 (US$10 billion), which made it the most damaging cyclone ever recorded in this basin.
