The Foley Shield is a rugby league competition in North Queensland administered by the Queensland Rugby League.
Prior to 1948 an inter-town competition known as the Carlton Cup was contested in North Queensland. This was revamped, and renamed in honour of Arch Foley, a member of the 1918 Townsville representative team that travelled north to Cairns, and south throughout Central Queensland. He was a founding member of the Townsville Souths rugby league club, and with later Australian Prime Minister Arthur Fadden formed the North Queensland Rugby League in 1919.
In 1948 the competition was structured into a Northern Zone (Cairns, Babinda, Tully and Eacham) and a Southern Zone (Mackay, Ayr and Townsville). The following year, a Central Zone (Herbert River, Charters Towers and Home Hill) was added. The grand final was played in Townsville, and was a highlight of the rugby league calendar.
The Foley Shield continued to be held annually until the introduction of the statewide Queensland Cup competition in 1996. In 2000 the competition was reinstated, and was contested by Cairns, Mackay and Townsville.
