Michael Jordan retired from professional basketball three times during his career:

• His first retirement was on October 6, 1993, when he was 30 years old. This decision came after winning three consecutive NBA championships with the Chicago Bulls and was influenced by a combination of physical and mental exhaustion, the tragic murder of his father earlier that year, and a loss of desire to play basketball

• Jordan returned to the NBA in March 1995 and played until his second retirement in January 1999 at age 36. He had completed another three-peat of NBA titles with the Bulls by then

• He made a final comeback with the Washington Wizards in 2001 and ultimately retired for the last time in April 2003 at the age of 40

Thus, Michael Jordan's final retirement from the NBA was at age 40 in 2003.
