天城文（देवनागरी devanāgarī）又称“天城体”是印度和尼泊尔的一种文本，用来书写印地语、梵语、尼泊尔语等语言。天城文最早出现在13世纪初，是城文变体之一，天城文是对城文的改良而成，改良后的城文为突出其神圣加多了个梵文“天”字（देव deva）成为天城文。城文来自笈多文，笈多文犹如印度的其他文本一样，源自于前3世纪的婆罗米文。现在亚洲不少民族使用的字母与天城文的关系密切，而从帕拉瓦文派生的文本则在缅甸、泰国、柬埔寨、老挝等地使用。

Devanagari (/ˌdeɪvəˈnɑːɡəriː/ DAY-və-NAH-gər-ee; Hindustani: [d̪eːʋˈnaːɡri]; देवनागरी devanāgarī a compound of "deva" [देव] and "nāgarī" [नागरी]), also called Nagari (Nāgarī, नागरी), is an abugida (alphasyllabary) alphabet of India and Nepal. It is written from left to right, has a strong preference for symmetrical rounded shapes within squared outlines, and is recognisable by a horizontal line that runs along the top of full letters. In a cursory look, the Devanagari script appears different from other Indic scripts such as Bangla, Oriya or Gurmukhi, but a closer examination reveals they are very similar except for angles and structural emphasis.
