The 1973 NBA draft was the 27th annual draft of the National Basketball Association (NBA). The draft was held on April 24 and May 5, 1973, before the 1973–74 season. In this draft, 17 NBA teams took turns selecting amateur U.S. college basketball players and other eligible players, including international players. The first two picks in the draft belonged to the teams that finished last in each conference, with the order determined by a coin flip. The Philadelphia 76ers won the coin flip and were awarded the first overall pick, while the Portland Trail Blazers were awarded the second pick. The remaining first-round picks and the subsequent rounds were assigned to teams in reverse order of their win–loss record in the previous season. Prior to the draft, the Baltimore Bullets relocated to Landover, Maryland, and became the Capital Bullets. The Philadelphia 76ers were awarded an extra first-round draft pick as compensation when the Seattle SuperSonics signed John Brisker. A player who had finished his four-year college eligibility was eligible for selection. If a player left college early, he would not be eligible for selection until his college class graduated. Before the draft, 11 college underclassmen were declared eligible for selection under the "hardship" rule. These players had applied and gave evidence of financial hardship to the league, which granted them the right to start earning their living by starting their professional careers earlier. The draft consisted of 20 rounds comprising the selection of 211 players.

The Philadelphia 76ers, also known colloquially as the Sixers, are an American professional basketball team based in the Philadelphia metropolitan area. The 76ers compete in the National Basketball Association (NBA) as a member of the Atlantic Division of the Eastern Conference. The team plays its home games at the Wells Fargo Center located in the South Philadelphia Sports Complex. Founded in 1946 and originally known as the Syracuse Nationals, they are one of the oldest franchises in the NBA and one of only eight of the 23 to survive the league's first decade. The team is owned and managed by Harris Blitzer Sports & Entertainment (HBSE), with founders Josh Harris and David Blitzer acquiring the team in 2011.
