The 1938 Auckland Rugby League season was its 30th. Marist Old Boys won their 3rd first grade title with their previous coming in 1924 and 1931. Richmond Rovers won the Roope Rooster for the 5th time when they beat City Rovers 20–8 in the final. City had not won a trophy since 1925 but had been boosted mid season by the addition of Bob Banham who the Auckland Rugby League had brought over from Australia as a player coach. Richmond also won the Stormont Shield for the 4th time when they defeated Marist Old Boys 9–8. Eastern Suburbs (NSWRL runner up) toured at the end of the season and Richmond were the only team to beat them when they won 11–9. Eastern Suburbs beat Marist (36-15), Manukau (16-7) and a South Auckland (Waikato) team (17-5).
