Several braille alphabets are used in Nigeria. For English, Unified English Braille has been adopted. Three other languages have been written in braille: Hausa, Igbo, and Yoruba. All three alphabets are based on English readings, with the addition of letter's particular to these languages. Punctuation is as in English Braille.
| a | b | c | d | e | f | g | h | i | j | k | l | m | |
| n | o | p | q | r | s | t | u | v | w | x | y | z |
The letters of these languages beyond the basic Latin alphabet are as follows:
| Hausa Braille | |

Hausa includes
| kw | sh | ts | ɗ |
from English q, sh, st, ed (international second d), and three derived letters:
| Basic letter: | b | k | y | |
|---|---|---|---|---|
| Derived letter: | ɓ | ƙ | ƴ |
Hausa is presumably written in braille in Niger as well, since Ethnologue 17 reports that Zarma is written in braille in that country. However, this need not mean it uses the same alphabet as Nigerian Hausa.
