Oldest players
The oldest player ever to play in the NBA was Nat Hickey who played one game in the 1947–48 season when he was 45 years and 363 days old. Hickey, who was coaching the Providence Steamrollers at the time, decided to activate himself and played in a game for the Steamrollers. In his first game as a player for the Steamrollers, he missed all six of his shot attempts and only scored two points from three free throw attempts; he only played in one more game before retiring as a player two days shy of his 46th birthday. The second-oldest player is Kevin Willis, who played 20 seasons (excluding the 1988–89 season he missed due to injury) in the league before he sat out the 2005–06 season and earned a contract with the Dallas Mavericks on April 2, 2007. Willis then played five games for the Mavericks at the age of 44. The third-oldest player is Hall of Famer Robert Parish. Parish, who played with the Boston Celtics in the 1980s, played his last season with the Chicago Bulls at the age of 43. He played in 1,611 regular season games during his 21-year career, more than any other player in NBA history. When the Bulls won the 1997 Finals, Parish became the oldest player ever to win the NBA championship. There are 31 players who played in the NBA after they turned 40. Following the retirements of the then-43-year-old Udonis Haslem and Andre Iguodala shortly after the 2022–23 season, the oldest active player is the aforementioned LeBron James.

Active
This list includes active players who are or will be at least 35 years old in the current season or year.

Youngest players
NBA players usually come from U.S. college basketball. In the past, a college player had to complete his four-year college eligibility before he could enter the league through the NBA draft or as a free agent. In the 1970s, the league began to allow college underclassmen and high school players to enter the league. However, the trend of drafting high school players only began in the mid 1990s. This has led to more younger players entering the league directly after high school graduation. In 2005, the league and the players' union agreed on a new collective bargaining agreement that includes a minimum age limit which requires that players who wish to enter the league must be at least 19 years old on December 31 of the year of the draft, and at least one year removed from high school. International players who did not play college basketball also have to be at least 19 years old on the same date to be able to play in the NBA. Despite a trend toward drafting younger players, the NBA has a higher average age than it had in the 1980s. However, since the NBA introduced the minimum age limit in 2005, the league's average age has decreased in the past few seasons. The youngest player to ever play in the NBA was Andrew Bynum who played his first game at the age of 18 years and 6 days old. Bynum, who was also the youngest player ever selected in the NBA Draft, went into the NBA straight out of high school. Jermaine O'Neal and Kobe Bryant, both drafted in 1996, were the second- and third-youngest players. Serbian Darko Miličić was the youngest player ever to play in an NBA Finals game. He played for the Detroit Pistons in Game 3 of the 2004 Finals at the age of 18 years and 356 days old. The Pistons won the 2004 Finals and Miličić became the youngest player ever to win the NBA championship, being only five days away from his 19th birthday at the time. There are currently 30 players who played in the NBA before they turned 19. Nineteen of them came to the league straight out of high school, while seven of them are international players who never played basketball in U.S. high schools or colleges before they entered the NBA, and four players, Devin Booker, Joshua Primo, Jalen Duren and GG Jackson played one year of college before entering the NBA all while remaining 18 years old throughout the process.
