Ā, lowercase ā, is a grapheme, a Latin A with a macron, is used in several orthographies.

In the Latvian alphabet, Ā represents a distinct vowel and comes after A and before B in alphabetical order: for instance baznīca comes before bārda in a Latvian dictionary. It is considered as a separate letter in the Latvian alphabet. Ā is used to denote a long A in Latvian.

In some languages Ā is used to denote a long A. Examples are the Polynesian languages, including Māori, some romanizations of Japanese (rōmaji) and Arabic, and some Latin texts (especially for learners). It is used in some orthography-based transcriptions of English to represent the diphthong [eɪ] ([eː] in some dialects), and also in commercial names such as Drāno and Powerāde.

In Pinyin, Ā denotes A in the first tone of Mandarin Chinese.

In all these languages, Ā is sorted with other As and is not considered a separate letter. The macron is only considered when sorting words that are otherwise identical. For example, in Māori, tāu (meaning your) comes after tau (meaning year), but before taumata (hill).
