Thái Ngọc (born 1942) is a Vietnamese insomniac. According to Vietnamese news organization Thanh Niên, he is best known for his claim of being awake for 46 years. Thanh Niên also claimed that Ngoc acquired the ability to go without sleep after a bout of fever in 1973, but according to the Vietnam Investment Review, there was no apparent cause.
At the time of the Thanh Niên report, Ngoc suffered from no apparent ill effect other than being unable to sleep. He was mentally sound and carried two 50 kg (110 lb) sacks of pig feed down a 5 km (3.1 mi) road every day.
In October 2006, however, Ngoc reported that he was beginning to feel "like a plant without water" due to the lack of sleep.
