The Metropolitan Association of Upper Silesia or Upper Silesian Metropolitan Union (), often referred to in Poland as Silesian Metropolis (), was a municipal association () composed of 14 adjacent cities with powiat rights of Katowice urban area in the Polish Silesian Voivodeship. The association existed from 2007 to 2017, when its role was effectively taken over by the Metropolis GZM.
The aim of the union was the creation of a strong metropolitan center with pooled resources, an internationally competitive profile and unified management of common infrastructure.
The main goals of the union included the following:

The effects of the union's activity included: improvement in managing the consortium, strengthening its economic muscle and increasing the competitive standing of the cities of the MAUS, coordination of public relations and promoting the member cities, and underscoring the importance of the region.
It was created by local authorities with little or no actual public discourse. The intent to form the union was formally stated by the mayors of the participating cities, who signed a declaration to this effect on 9 January 2006 in à ÂwiÃÂtochà Âowice. The Union's registration was signed by the Ministry of Internal Affairs and Administration of the Republic of Poland (Polish: MSWiA) on 8 June 2007 with the city of Katowice.
On 1 July 2017 a new sui generis entity, the Metropolis GZM (), was created. Therefore, the Metropolitan Association of Upper Silesia was discontinued on 28 December 2017.
Originally 17 cities were to enter into the union; only 14 of the 17 cities (that is, those with the legal status of a City with powiat rights) proceeded with forming the union. Towns of BÃÂdzin, Czeladà º and Knurów canceled their candidacy.

The constituent cities by population numbers were as follows (data of 2008):
