NKo (ߒߞߏ), also spelled N'Ko, is an alphabetic script devised by Solomana Kanté in 1949, as a modern writing system for the Manding languages of West Africa. The term NKo, which means I say in all Manding languages, is also used for the Manding literary standard written in the NKo script.

In a right-to-left, top-to-bottom script, writing starts from the right of the page and continues to the left, proceeding from top to bottom for new lines. Arabic, Hebrew, and Persian are the most widespread RTL writing systems in modern times.
