The 2004 NBA Draft was held on June 24, 2004 at The Theater at Madison Square Garden in New York City, New York and was broadcast live on ESPN at 7:00 pm (EDT). In this draft, National Basketball Association teams took turns selecting amateur college basketball players and other first-time eligible players. The NBA announced that 56 college and high school players and 38 international players had filed as early-entry candidates for the 2004 draft. On May 26, the NBA Draft Lottery was conducted for the teams who did not make the NBA Playoffs in the 2003-04 NBA season. The Orlando Magic, who had a 25 percent chance of obtaining the first selection, won the lottery, while the Los Angeles Clippers and the Chicago Bulls were second and third respectively. As an expansion team, the Charlotte Bobcats had been assigned the fourth selection in the draft and did not participate in the lottery. The Minnesota Timberwolves forfeited their first-round pick due to salary cap violations.

After the completion of the regular season, Emeka Okafor, the Bobcats' historical first rookie draft pick, was named Rookie of the Year, while Ben Gordon earned the Sixth Man Award, becoming the first rookie in NBA history to do so.

The NBA Draft is an annual event in which the thirty teams from the National Basketball Association (NBA) can draft players who are eligible and wish to join the league. These players are usually amateur U.S. college basketball players, but international players are also eligible to be drafted. College players who have finished their four-year college eligibility are automatically eligible for selection, while the underclassmen have to declare their eligibility and give up their remaining college eligibility. International players who are at least 22 years old are automatically eligible for selection, while the players younger than 22 have to declare their eligibility. Players who are not automatically eligible but have declared their eligibility are often called "early-entrants" or "early-entry candidates". The Draft usually takes place at the end of June, during the NBA off-season. The Draft consists of two rounds with a total of sixty players to be selected.

In the past, high school players were also eligible to be selected. However, starting in the 2006 Draft, high school players were not eligible to enter the draft directly after graduating high school. The rules now state that high school players will gain eligibility for draft selection one year after their high school graduation and they must also be at least 19 years old as of the end of the calendar year of the draft. Contrary to popular belief, they do not necessarily have to have at least one year of college basketball (as some players have chosen to use that year to play professionally in Europe for example).

LeBron Raymone James (/ləˈbrɒn/; born December 30, 1984) is an American professional basketball player for the Miami Heat of the National Basketball Association (NBA). Nicknamed "King James", he was a three-time "Mr. Basketball" of Ohio in high school, and was highly promoted in the national media as a future NBA superstar while a sophomore at St. Vincent – St. Mary High School. He was selected with the number one pick in the 2003 NBA Draft by the Cleveland Cavaliers. Listed as a small forward, James has set numerous youngest player records since joining the league. He was named the NBA Rookie of the Year in 2003–04, was named the NBA Most Valuable Player in 2009, 2010, and 2012 and has been both an All-NBA selection and an All-Star every season since 2005. In 2010, a much-publicized free agency process ended with James signing with the Miami Heat.

James led the Cleveland Cavaliers to consecutive playoff appearances from 2006 through 2010. In 2007, the Cavaliers advanced to the NBA Finals for the first time in franchise history, but lost to the San Antonio Spurs. In 2011, James and the Miami Heat advanced to the NBA Finals but lost to the Dallas Mavericks. James has been a member of the USA national team, winning a bronze medal at the 2004 Olympics and gold at the 2008 Olympics.
