The 1980–81 NBA season was the fifth season in the NBA, the seventh in San Antonio and the 13th as a franchise. It was a landmark season in many ways. The San Antonio Spurs moved to the Western Conference along with the Houston Rockets. The Spurs won their first Midwest Division title, and their third division title overall (they had won the Central Division in 1977-78 and 1978–79). The Spurs had the fourth best team offensive rating in the NBA.
