马佐夫舍（波兰语：Mazowsze）是历史上位于波兰东部的一个地区，首府华沙。

10世纪，梅什科一世征服马佐夫舍，成为波兰历史上第一位统治者。随着1034年梅什科二世逝世和波希米亚人入侵，马佐夫舍获得了短暂的独立。1047年，卡齐米日一世在鲁塞尼亚人的帮助下将马佐夫吉置于统治之下。

12世纪，随着博莱斯瓦夫三世逝世，波兰分裂，马佐夫舍处于博莱斯瓦夫四世及随后的马佐夫舍公爵统治之下。1526年，最后一位公爵逝世，马佐夫舍重归波兰王国。

18世纪，波兰第三次分裂，马佐夫舍先后于1815年与1831年加入波兰会议王国和俄罗斯帝国。1918年，马佐夫舍成为波兰第二共和国的一部分。

Mazovia (Polish:Mazowsze) is a historical region (dzielnica) in mid-north-eastern Poland. Borders of the Mazovian Voivodeship, which was created in 1999, do not reflect exactly its original shape (they do not include historically Mazovian Łomża and Łowicz, meanwhile include Lesser Polish Radom and Siedlce), but are roughly similar. Historical Mazovia existed since the Middle Ages until the partitions of Poland and consisted of three voivodeships with the capitals in Warszawa, Płock and Rawa Mazowiecka. In a narrower sense, the Mazovian Voivodeship was only the first of them (which however encompassed most of the region, only without the western lands). Between 1816 and 1844 another Mazovian Voivodeship (from 1837 Governorate) existed, encompassing the south of the region (along with Łęczyca Land and south-eastern Kujawy). In the Middle Ages the main city of the region was Płock, but in the Early Modern Times it lost importance in favour of Warsaw. Since 1138 Mazovia had a separate branch of the Piast dynasty and was incorporated to the Polish Crown as late as in the 15th and 16th centuries. As much as over 20% of Mazovian population was the yeomanry (drobna szlachta). Inhabitants of Mazovia are Mazurzy (in the singular: Mazur) – hence the region of Masuria, settled by them.
