阿尼（Ani），土耳其卡尔斯省的一个中世纪的废墟和无人居住的亚美尼亚城市，靠近亚美尼亚边境。它曾是一个中世纪亚美尼亚王国的首都，这个昔日的国家管辖的区域包括如今亚美尼亚和土耳其东部大部分地区。该城市位于一个三角地带，东边的河流和西边的山谷构成天然屏障。阿尼被称为“1001个教堂之城”，位于多条贸易通路上，有许多宗教建筑、宫殿和防御工事，其中的一些曾经是当时世界上最先进的技术和艺术性。

在鼎盛时期，阿尼拥有10-20万居民，地位相当于于同期的君士坦丁堡、巴格达和开罗。 几个世纪之前，阿尼被废弃和遗忘。

Ani (Armenian:Անի; Greek: Ἄνιον, Ánion; Latin:Abnicum; Georgian:ანისი, Anisi; Turkish:Ani) is a ruined medieval Armenian city situated in the Turkish province of Kars near the border with Armenia.

Between 961 and 1045, it was the capital of the Bagratid Armenian kingdom that covered much of present-day Armenia and eastern Turkey. Called the "City of 1001 Churches", Ani stood on various trade routes and its many religious buildings, palaces, and fortifications were amongst the most technically and artistically advanced structures in the world. At its height, the population of Ani probably was on the order of 100,000.
