Robert Newton Lowery (July 13, 1882—April 27, 1962) was a politician in Manitoba, Canada. He served in the Legislative Assembly of Manitoba from 1915 to 1920 as a member of the Liberal Party.
Lowery was born in Detroit, Michigan, the son of Edward Wesley Lowery and Christina Elizabeth Maguire, and moved to Canada with his family in 1883. He attended public schools in Winnipeg. He first worked as an employee of the Canadian Pacific Railway and later worked as a real estate agent and broker. In 1909, Lowery married Gertrude Bowman. In religion, he was a Methodist. He was chair of the Selkirk Board of Management, and a director of the Young Men's Christian Association.
Lowery first ran for the Manitoba legislature in the 1914 provincial election, and lost to Conservative candidate Daniel McLean by 623 votes in the Winnipeg North's "B" constituency. He contested Winnipeg North "A" in the 1915 election, and defeated Social Democratic candidate Arthur Beech by 195 votes (Conservative incumbent Joseph P. Foley finished third). The Liberals won a landslide majority in this election, and Lowery served as a backbench supporter of Tobias Norris's administration for the next five years.
