Metro Davao, officially Metropolitan Davao (Cebuano: Kaulohang Dabaw; Filipino: Kalakhang Davao), is a metropolitan area in Mindanao, Philippines. It includes the cities of Davao, Digos, Panabo, Samal and Tagum and spans parts of all five provinces of the Davao Region. Metro Davao is one of three metropolitan areas in the Philippines. It is administered by the Metropolitan Davao Development Authority. It is the largest metropolitan region by land area and the second most populous in the Philippines.

The agglomeration of Metro Davao has no formal legal framework early on its initial stage of development process either by an act of Congress, by an executive declaration of the president or by a formal agreement among component cities and municipalities of the metropolitan area.

In the case of Metro Manila, the component cities and municipalities were grouped into a province through a decree issued by then-President Ferdinand Marcos, and designated the then First Lady Imelda Marcos as a governess. From then on, Greater Manila, as it was known earlier, became Metro Manila.

To formalize its juridical identity, Congress passed into law Republic Act No. 7924, instituting the Metropolitan Manila Development Authority. Under the current law, the head of the agency shall be appointed by the President and should not be on a concurrent elected position as mayor.

Metro Cebu is a concept created in the 70's and formally adopted by the Regional Development Council of Central Visayas as a platform for integrating parallel development in the metropolitan area.

Although Metro Davao was formed in 1995 by then-mayor of Davao City (and later president) Rodrigo Duterte, it does not have the birth perspective of either Metro Cebu or Metro Manila. The metropolitan concept of Metro Davao is being spearheaded by the mayor but no formal agreement or an act of congress have been executed to formalize its legal and juridical identity. Because of this, the region, having no official legal framework (although they have a de facto one, the Davao Regional Development Council), exists not as a juridical identity but only as an informal reference to the area. However, the said council have formally adopted the concept in 1996 for the development of the area, especially Davao City.

Twenty-seven years later, as president, Duterte signed Republic Act No. 11708 on April 27, 2022, paving the way for the establishment of the Metro Davao Development Authority which would oversee the administration and planning in the metropolitan area.

Prior to the creation of the Metropolitan Davao Development Authority in 2022, Metro Davao had its three own development and governance councils, namely: Davao Integrated Development Program Board, Metropolitan Davao Committee, and Metropolitan Davao Management Office. Davao Integrated Development Program Board served as the metropolitan area's development council, since Metro Davao not only defines the LGUs in the said metropolitan area, but also all of Davao Region. As such, it was not an administrative political unit but an agglomeration of independent local government units, the third level government in the Philippine political system. With Republic Act No. 11708 signed into effect in 2022 however, the then newly created Metropolitan Davao Development Authority will replace the provisional entities that are overseeing the affairs of the metropolis, thus effectively turning Metro Davao into an administrative political unit in the same level as Metro Manila. It is considered to be a special development and administrative region.
