Canadian syllabic writing, or simply syllabics, is a family of writing systems used in a number of Indigenous Canadian languages of the Algonquian, Inuit, and (formerly) Athabaskan language families. These languages had no formal writing system previously. They are valued for their distinctiveness from the Latin script and for the ease with which literacy can be achieved. For instance, by the late 19th century the Cree had achieved what may have been one of the highest rates of literacy in the world.

Syllabics are abugidas, where glyphs represent consonant-vowel pairs. They derive from the work of James Evans.

Canadian syllabics are currently used to write all of the Cree languages from Naskapi (spoken in Quebec) to the Rocky Mountains, including Eastern Cree, Woods Cree, Swampy Cree and Plains Cree. They are also used to write Inuktitut in the eastern Canadian Arctic; there they are co-official with the Latin script in the territory of Nunavut. They are used regionally for the other large Canadian Algonquian language, Ojibwe, as well as for Blackfoot, where they are obsolete. Among the Athabaskan languages further to the west, syllabics have been used at one point or another to write Dakelh (Carrier), Chipewyan, Slavey, Tłı̨chǫ (Dogrib) and Dane-zaa (Beaver). Syllabics have occasionally been used in the United States by communities that straddle the border, but are principally a Canadian phenomenon.
