Arthur Ernest Moore (February 12, 1882—1950) was an English-born politician in Manitoba, Canada. He served in the Legislative Assembly of Manitoba from 1920 to 1922 as a member of the Labour Party.
Moore was born in Lewisham and was educated at All Saints in Sydenham, in the southern suburbs of London, England. He moved to Canada in 1910. He served as a Signal Sergeant in the 44th Battaltion of the C.E.F. in World War I, and was wounded twice.
He was elected to the Manitoba legislature in the 1920 provincial election for the constituency of Springfield, east of Winnipeg. Moore defeated Farmer candidate Isaac Cook by 59 votes, and served with the opposition Labour parliamentary group for the next two years.
It is not clear what role he played in the Labour Party's divisions of late 1920, though, in any event, he did not seek re-election in 1922.
In the 1927 provincial election, an "A.E. Moore" sought election in Winnipeg as an independent supporter of the pro-temperance "Moderation League". At the time, Winnipeg elected ten members via a single transferable ballot. Moore finished eighteenth on the first count, and was eliminated on the tenth. It is likely that this "A.E. Moore" was the former Member of the Legislative Assembly (MLA).
