Northeastern Ontario is a secondary region of Northern Ontario in the Canadian province of Ontario, which lies north of Lake Huron and east of Lake Superior.^[1]

Northeastern Ontario consists of the districts of Algoma, Sudbury, Cochrane, Timiskaming, Nipissing and Manitoulin. For some purposes, Parry Sound District and Muskoka District Municipality are treated as part of Northeastern Ontario although they are geographically in Central Ontario. These two divisions are coloured in green on the map.

Northeastern Ontario and Northwestern Ontario may also be grouped together as Northern Ontario. An important difference between the two sub-regions is that Northeastern Ontario has a sizable Franco-Ontarian population — approximately 25 per cent of the region's population speaks French as a first language, compared with 3.2 per cent in the northwest.^[2] Virtually the entire region, except only the Manitoulin District, is designated as a French-language service area under Ontario's French Language Services Act. In the northwest, by contrast, only a few standalone municipalities are so designated.

In 2023, the Northeastern Ontario Tourism agency launched a social media marketing campaign, branding the region as "The Seven" in reference to the 705 telephone area code and the common nickname of Toronto as "The Six".^[3]
