United States/State boundary relations
|Part of United States mapping project.|
See WikiProject United States/Boundaries for information about boundary relations in the United States.
|State or territory||Relation|
|District of Columbia|
|Northern Mariana Islands|
|United States Virgin Islands|
|United States Minor Outlying Islands†|
• Note: Coastal states may not have all their islands included in the boundary relation.
† Note: Strictly speaking, USMOI is not an administrative boundary, it is a statistical grouping of eight Pacific Ocean islands or island groups and one island in the Caribbean Sea, each of which is a territory. However, it is convenient, as all are grouped into a single relation. These islands are uninhabited, except for several score of non-permanent federal personnel and support staff on three islands (Midway's Sand Island, Palmyra and Wake).
