In political geography, an enclave is a piece of land belonging to one territory that is totally surrounded by another territory. An exclave is a piece of land that is politically attached to a larger piece but not physically contiguous with it (connected to it) because they are completely separated by an unrelated territory or territories. Many entities are both enclaves and exclaves.

Enclaves that are also exclaves Each enclave listed in this section has an administrative level equivalent to that of the one other entity that entirely surrounds it. Each enclave is also a part of a main region; hence, it is an exclave of that region.

Vinokurov (2007) states, "For all purposes, a connection in a single point does not mean anything. It is just like being completely separated. One cannot pass through a single point, nor is it possible to transport goods. It is not even possible to lay a telephone line."Barkhudarli ~10 (Qazakh District) (Tavush Province) Controlled by Armenia since the First Nagorno-Karabakh War in May 1992; west-southwest of the town of Qazax.Yukhari Askipara ~28 A destroyed village controlled by Armenia since the First Nagorno-Karabakh War in May 1992; west of the town of Qazax.Karki / Tigranashen 8 (Nakhchivan Autonomous Republic, Sadarak District) (Ararat Province) Controlled by Armenia since the First Nagorno-Karabakh War in May 1992; north of Azerbaijan's exclave of Nakhchivan.Yaradullu (north and south)0.12 and 0.06 (Ağstafa District) (Tavush Province) Two farmland enclaves just across the border from the village of Yaradullu (55 m at the closest point). They are 750 m and 1500 m southwest of the municipality of Tatlı on the west bank of the Akhum River; approximately 300x400 m and 300x200 m. The surrounding Armenian territory has been occupied by Azerbaijan since the First Nagorno-Karabakh War in May 1992, so that these two small pockets of land are de facto no longer exclaves.Dahagram-Angarpota 25.95 (Rangpur Division – Lalmonirhat district) (West Bengal state – Cooch Behar district) Dahagram–Angarpota is a composite enclave of two adjoining chhits. It is separated from the contiguous area of Bangladesh at its closest point by . The enclave has an estimated population of 20,000. After the exchange of enclaves with India under the Land Boundary Agreement on 31 July 2015, Bangladesh retained it as an exclave. The Tin Bigha Corridor, a strip of Indian territory wide running from the enclave to the Bangladesh mainland at its nearest approach, was leased to Bangladesh in perpetuity for access to the enclave.Baarle-Hertog (22 parcels) 2.3448 (Antwerp province – Baarle-Hertog municipality) (North Brabant province – Baarle-Nassau municipality) (H1) A group of 22 Belgian enclaves in the southern Netherlands.

It deemed one of Quitasueño's 54 features to be an island at high tide (elevation 70 cm, area 1 m2) and created enclaves as an equitable solution. The area of Quitasueño, excluding the 12-mile zone, is ~290 km2. The land area of Serrana is ~0.11 km2, and the area of the bank, excluding the 12-mile zone, is ~322 km2. Colombia decried the loss of maritime areas and creation of "'enclaves' around Quitasueño and Serrana that could restrict" access.Serrana ~2,800, including water area (Southwest Cay)Brezovica Žumberačka (2) 0.0183+ (Karlovac County – Ozalj town) (Metlika municipality) The first enclave contains four dwellings surrounded by agricultural land near the Slovenian village of Brezovica pri Metliki.
