The 1983 NSWRFL season was the 76th season of professional rugby league football in Australia. Fourteen teams competed for the J J Giltinan Shield and Winfield Cup during the season, which culminated in a replay of the previous year's grand final between the Parramatta and Manly-Warringah clubs. During the season, NSWRFL teams also competed for the 1983 KB Cup.
1983 was the final season in the New South Wales Rugby Football League premiership for Sydney-based foundation club Newtown Jets, and the first reduction in the number of teams in the competition since Sydney University's departure at the end of the 1937 NSWRFL season. It was also the first season that was played with four-point tries.
