The Bassa script, known as Bassa vah or simply vah (meaning 'throwing a sign' in Bassa), is an alphabetic script used for writing the Bassa language of Liberia. The Bassa language is a vocalic-consonantal language.

The origin of the script is unclear. It is believed that the Bassa people may have had their own script that was forgotten in Liberia but used by ex-slaves in Brazil and the West Indies. It was later reinvented or possibly created by Dr. Thomas Flo Lewis, although it is uncertain. The first book written using the Bassa script was printed in 1907.

However, over time, the use of the Bassa script declined, and it was eventually replaced with the  International Phonetic Alphabet (IPA). 0070–02AF
