阿兰布拉宫（阿拉伯语：الحمراء‎，拉丁化：Al Ħamrā'；即红色城堡、红宫）是一个位于西班牙南部格拉纳达摩尔王朝时期修建的古代清真寺—宫殿—城堡建筑群。阿兰布拉宫最初的原址建有要塞称为Al-Andalus，宫殿为原格拉纳达摩尔人国王所建，现在则是一处穆斯林建筑、文化博物馆。1232年在老城改建的基础上逐步形成现存规模。宫墙外围有30米高的石砌城墙。有两组主要建筑群：一组为“石榴院”，另一组为“狮子院”。

统治格拉纳达的奈斯尔王朝（Nasrid dynasty）的第一代统治者穆罕穆德一世（Mohammed I ibn Nasr）修建了阿兰布拉宫，因穆罕穆德被称为“红人之子”，这座宫殿又叫作“红宫”。其作为伊斯兰教世俗建筑与造园技艺完美结合的建筑名作以及阿拉伯式宫殿庭院建筑的优秀代表，1984年被选入联合国教科文组织世界文化遗产名录之中。

The Alhambra (/ælˈhæmbrə/; Spanish: [aˈlambɾa]; Arabic:الْحَمْرَاء‎ [ʔælħæmˈɾˠɑːʔ], Al-Ḥamrā, lit. "The Red One"), the complete Arabic form of which was Calat Alhamra, is a palace and fortress complex located in Granada, Andalusia, Spain. It was originally constructed as a small fortress in AD 889 on the remains of Roman fortifications and then largely ignored until its ruins were renovated and rebuilt in the mid-13th century by the Moorish emir Mohammed ben Al-Ahmar of the Emirate of Granada, who built its current palace and walls. It was converted into a royal palace in 1333 by Yusuf I, Sultan of Granada. After the conclusion of the Christian Reconquista in 1492, the site became the Royal Court of Ferdinand and Isabella (where Christopher Columbus allegedly received royal endorsement for his expedition) and the palaces were partially altered to Renaissance tastes. In 1526 Charles I & V commissioned a new Renaissance palace better befitting of the Holy Roman Emperor in the revolutionary Mannerist style influenced by Humanist philosophy in direct juxtaposition with the Nasrid Andalusian architecture, but which was ultimately never completed due to Morisco rebellions in Granada.
