Joseph Crawford (born August 30, 1951 in Havertown, Pennsylvania) is an American retired professional basketball referee who worked in the National Basketball Association (NBA) between 1977 and 2016. Crawford, who wore uniform number 17, was regarded as one of the strictest and most controversial officials in the NBA and developed a reputation for assessing technical fouls against both players and coaches. As of the conclusion of the 2014–15 NBA season, Crawford had worked more playoff (313) and NBA Finals games (50) than any other active referee in the league. He officiated in every NBA Finals series from 1986 to 2015, only missing 2007 due to suspension. In addition to playoff games, Crawford officiated the NBA All-Star Game in 1986, 1992 and 2000.
