省或行省（奥斯曼土耳其语：ایالت，土耳其语：Eyalet，土耳其语发音：[ejaːˈlet]，埃亚莱特），或被称为贝勒贝伊里克或帕夏里克，奥斯曼帝国的1876年行政区划改革之前的第一级行政区划。

从1453年到19世纪初，奥斯曼的地方政府组织都很松散。该帝国的一级区划为省（Eyalet），由三马尾帕夏统领。由帝国宰相“大维齐尔”提名首都和各省所有的高级官员。在1861年至1866年间，各省被废除，为便于管理，其辖区被分为多个州（Vilayet，维拉耶）。

每个省份被划分为多个旗（突厥语称“桑贾克”，阿拉伯语称“里瓦”），各旗长官为一马尾帕夏，称号为“米拉-利拉”或“桑贾克贝伊”。这个省份通常被欧洲人称为“帕夏里克”（或译为帕夏辖区）。帕夏被赋予了绝对的行政权力，在其省份之内，无论军事、经济还是治安、司法都受他管理。

Eyalets (Ottoman Turkish:ایالت‎ Turkish pronunciation: [ejaːˈlet]), (English: State) also known as beylerbeyliks or pashaliks, were a primary administrative division of the Ottoman Empire.

From 1453 to the beginning of the nineteenth century the Ottoman local government was loosely structured. The Empire was at first divided into provinces called eyalets, presided over by a Pasha of three tails (feathers borne on a state officer's ceremonial staff). The Grand Vizier was responsible for nominating all the high officers of State, both in the capital and the provinces. Between 1861 and 1866, these Eyalets were abolished, and the territory was divided for administrative purposes into Vilayets.
