Latin beta (uppercase: Ꞵ, lowercase: ꞵ), is a letter of the Latin script.

Its shape, in uppercase and lowercase, is based on the lowercase shape of the letter beta from the Greek alphabet (β).

[1] It is not typographically and linguistically related to the similar looking letter eszett (ẞ, ß) used in writing German, which represents an /s/ sound.

The letter is used in the scientific alphabet of the languages of Gabon used for Pinji, Benga, Barama, Galwa, Viya, Kande, Kaning'i, Lumbu, Myene, Ndumu, Ngom, Njebi, Vove, Punu, Sangu, Shira and Vumbu languages.

Additionally, it has been used in 2013 in the alphabet made by Émile Gille Nguendjio for the Ndaʼndaʼ language, for example in the word káꞵé ([ka˥βe˥]), which means "cover".
