Amazing Grace is most popularly sang in French in Haiti.

You will find the French lyrics at #98 of the Melodies Joyeuses (the blue pages of the Chants D’Esperance)

A few churches do sing the Creole version.

Here it is in Creole and French.

Creole

Gras enfini, ala yon don!

Pou mwen pechè ki kwè

Mwen te pèdi, mwen genyen padon

Mwen t’avèg, men mwen wè

Gras la mete lakrent nan mwen

E li te delivre m

Ala yon gras presiye pou mwen

Lè’m te lage’m nan men l

French

Grâce enfinie, ô quel beau don

Pour moi pécheur qui crois;

J’étais perdu, j’ai le pardon

Aveugle, mais je vois

La grâce a mis la crainte en moi

Et m’en a délivré

O grâce précieuse à ma foi

Lorsque j’y ai cédé

Au travers des temps infinis

Les chants de tes élus

Seront toujours ta grâce ô Christ
