Mandombe or Mandombé is a script proposed in 1978 in Mbanza-Ngungu in the Bas-Congo province of the Democratic Republic of the Congo by Wabeladio Payi, who related that it was revealed to him in a dream by Simon Kimbangu, of the Kimbanguist Church.

Mandombe is based on the sacred shapes and , and intended for writing African languages such as Kikongo, as well as the four national languages of the Congo, Kikongo ya leta, Lingala, Tshiluba and Swahili, though it does not have enough vowels to write Lingala fully.

The Mandombe Academy at CENA is currently working on transcribing other African languages in the script.

[2] A preliminary proposal has been made to include this script in the combined character encoding ISO 10646/Unicode.

[3] A revised Unicode proposal was written in February 2016 by Andrij Rovenchak, Helma Pasch, Charles Riley, and Nandefo Robert Wazi.

While there is a diacritic for u, sequences ending in u are instead generally written as two full syllables, the second being wu.

The use of geometric transformation is also present in Pitman shorthand and Canadian Aboriginal Syllabics, though Mandombe consonants in the same group do not seem to have any phonological relationship (except the fifth group named mazita ma zindinga, in which all consonants are affricates and fricatives).
