Factory Island 1 is a Cree First Nations reserve on Moose Factory Island in northern Ontario. It is one of two reserves for the Moose Cree First Nation.
The northern two-thirds of the island comprises this reserve or land north of Museum Street. Most residential, the reserve is home to a Northern Store, Cree Interpretative Centre and Treeline Diner. Key government services, including the hospital, are located in the southern part of the island under the Unorganized North Cochrane District.
Half of the reserve, namely the north end is tree covered land.
Gravel roads are used for vehicles within town. There are no bridges, but an ice road is available during the winter season.
The reserve and the Moosonee area has a very cold humid continental climate (Köppen Dfb). The climate data is from Moosonee, around to the west. <div style=width:79%> </div>
