Alfred "Butch" Lee Jr. is a Puerto Rican former professional basketball player. Lee was the first Puerto Rican and first Latin American-born athlete to play in the National Basketball Association (NBA), accomplishing this after being selected in the first round of the 1978 NBA draft.

The 1978 NBA draft was the 32nd annual draft of the National Basketball Association (NBA). The draft was held on June 9, 1978, at the Plaza Hotel in New York City, New York, before the 1978–79 season. In this draft, 22 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 Indiana Pacers won the coin flip and were awarded the first overall pick, while the Kansas City Kings, who obtained the New Jersey Nets' first-round pick in a trade, were awarded the second pick. The Pacers then traded the first pick to the Portland Trail Blazers before the draft. 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. 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, five 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. Prior to the start of the season, the Buffalo Braves relocated to San Diego and became the San Diego Clippers. The draft consisted of 10 rounds comprising the selection of 202 players.
