According to the Bible, Noah lived approximately 1,500 years after Creation. The 10th patriarch in order from the beginning of time, Noah lived to be 950 years old, according to Genesis 9:29.
Noah was the son of Lamech and the grandson of Methusaleh, who is known for being the longest living man in the Bible at 969 years. Answers in Genetics notes that after the flood, patriarchs were not known to live quite as long, with Abraham living to the age of 175. It is believed that the flood may have biologically changed the Earth in ways that affected the lifespan of humans.
