Mowbray is an unincorporated community in Division No. 4, Manitoba, Canada.
Located on the border with North Dakota, the settlement thrived during the early 1900s and prohibition, but only one family lived here in the 1980s.
Settlers from Ontario arrived here in the early 1880s.
In 1884, a post office was established, and Mowbray School was built "a mile away" from the settlement. A customs office at the crossing into the United States opened in 1899; it was replaced by a customs office in nearby Snowflake in 1908.
Canadian Pacific Railway arrived in 1902 and the railway station helped Mowbray. The settlement had a general store, a hotel, a livery and blacksmith, two grain elevators, a jail and Jackson community cemetery.
In 1906, Mowbray's school was replaced by two new ones. The first school kept the name Mowbray, and the second one room school, Boundary School, had its water and some of its students supplied from North Dakota. Residents from Mowbray regularly crossed into North Dakota to shop and sell farm produce, and the liquor business thrived during Prohibition in the United States from 1920 to 1933.
Mowbray began to decline in 1935 when railway service was reduced to once a week. Mowbray School closed in 1956, Boundary School closed after fifty years of service, and the railway was abandoned in 1963. In the 1980s, one family was living in Mowbray.
Boundary, the second Mowbray School is listed as a Manitoba Provincial Heritage Site.
James Leland Sims, who was born here in 1905, became a member of the Legislative Assembly of Alberta.
