| Parallel | Description |
|---|---|

| 74°N | |
| 70°N | On Victoria Island, Canada, two sections of the border between Northwest Territories and Nunavut. |
| 60°N | In Canada, the southern border of Yukon with the northern border of British Columbia; the southern border of Northwest Territories with the northern borders of British Columbia, Alberta and Saskatchewan; and the southern border of mainland Nunavut with the northern border of Manitoba, leading to the expression "north of sixty" for the territories. |
| 54°40'N | The border between 19th century Russian territories to the north and conflicting American and British land claims in western North America. The conflicting claims led to the Oregon boundary dispute between Britain and the United States, giving rise to the slogan "Fifty-four forty or fight." |
| 52°N | In Canada, part of the border between Newfoundland and Labrador and Quebec. |
| 51°N | The southern limit of Russian America from 1799 to 1821. |
| 49°N | Much of the border between Canada and the United States, from British Columbia to Manitoba; "49th parallel" is a common expression for the border, though the majority of Canada's population actually lives south of the parallel. |
| 48°N | In Canada, part of the border between Quebec and New Brunswick. |
| 46°N | In the United States, part of the border between Washington and Oregon. |

| 41°N | In the US, part of the border between Wyoming and Utah, the border between Wyoming and Colorado, and part of the border between Nebraska and Colorado. |
| 40°N | In the US, the border between Nebraska and Kansas. The parallel was originally chosen for the Mason–Dixon line, but the line was moved several miles south to avoid bisecting the city of Philadelphia. |

| 20°N | A short section of the border between Libya and Sudan, and within Sudan, the northern border of the Darfur region. |
| 17°N | The division between Republic of Vietnam (South Vietnam) and Democratic Republic of Vietnam (North Vietnam) during the Vietnam War. |
| 15°N | de facto maritime border between Honduras and Nicaragua. |
