The 1927 Auckland Rugby League season was its 18th. Newton defeated Ponsonby by 6 points to 3 in the championship final to win the Monteith Shield after both teams finished the season tied with identical 8 win, 1 draw, 3 loss records. This was the second time Newton had won the championship in 18 efforts, with the first being in 1912 and was to be their last after they merged decades later with City Rovers and the combined team ceased in the early 2000s. Richmond won the Roope Rooster knockout trophy for the second consecutive season. Newton Rangers defeated Richmond to win the Stormont Shield.
