The Sports and Recreation Center (, OSiR) is an entity dedicated to promoting physical culture, sports, and recreational activities among the residents of a particular locality, primarily in Poland. Its responsibilities include maintaining sports facilities, managing sports sections, and organizing competitions at local and higher levels. In many cities, such centers operate under the name Municipal Sports and Recreation Center (, MOSiR).

These centers are typically public entities funded by local government budgets, sponsor donations, and subsidies from the European Union.
