The 1919 season of the Auckland Rugby League was its 11th. It was the first season post World War I and unsurprisingly it saw a resurgence in playing numbers with 56 teams across the six grades. North Shore Albions who had previously dropped out of the senior competition again fielded a senior side. As did Otahuhu, who had dropped out during the 1917 season. Ponsonby United won their third consecutive first grade title, while Newton Rangers won the Roope Rooster trophy.
The season was also summarised by the league as well. Forty-nine teams were entered across all grades. Sunnyside won the second grade, Manukau won the third grade, City won the fourth and fifty grades, while Ponsonby won the sixth grade. It was stated that the standard of play in the senior club competition was not as good as it would have been due to the fact that 19 of the best club players from Auckland were away for a large part of the season representing New Zealand in Australia.
