Ogahalla is an unincorporated place and railway point in geographic Barlow Township[1][2] in the Unorganized North Part of Cochrane District in northeastern Ontario, Canada.

[3] It is on a now abandoned portion of the Canadian National Railway main line originally constructed as the National Transcontinental Railway transcontinental main line,[4] between the railway points of Lynx to the west and Blanche to the east, 4 kilometres (2 mi) west of where the line crossed the Kenogami River.

A now abandoned airfield, created by the Department of National Defence[5] in the mid-1930s in part using 22,632 person-days of unemployment relief labour,[6] lies to the north of the place.

A Frontier College instructor was located at the construction camp.

[5] The airfield became in the late 1930s part of a string of emergency landing sites for Trans-Canada Air Lines (today Air Canada) to support their transcontinental flight operations.
