纳巴泰字母（Nabataean alphabet）是公元前2世纪时纳巴泰人使用的辅音音素文本， 相关的铭刻在佩特拉发现。纳巴泰字母是从亚兰字母经古叙利亚字母演变而成的，其后在公元4世纪发展成阿拉伯字母， 因此其字形介乎闪米特字母（如希伯来字母）和阿拉伯字母之间。

The Nabataean alphabet is a consonantal alphabet (abjad) that was used by the Nabataeans in the 2nd century BC. Important inscriptions are found in Petra, Jordan. The alphabet is descended from the Syriac alphabet, which was itself descended from the Aramaic alphabet. In turn, a cursive form of Nabataean developed into the Arabic alphabet from the 4th century, which is why Nabataean's letterforms are intermediate between the more northerly Semitic scripts (such as the Aramaic-derived Hebrew) and those of Arabic.
