Mi'kmaw hieroglyphic writing or Suckerfish script (Mi'kmawi'simk: Gomgwejui'gasit) was a writing system for the Mi'kmaw language, later superseded by various Latin scripts which are currently in use. Mi'kmaw are a Canadian First Nation whose homeland, called Mi'kma'ki, overlaps much of the Atlantic provinces, specifically all of Nova Scotia, Prince Edward Island, and parts of New Brunswick and Newfoundland and Labrador.
These glyphs, or gomgwejui'gaqan, although unrelated, followed a prior pictograph and petroglyph tradition, and are logograms, with phonetic elements used alongside, including logographic, alphabetic, and ideographic information. As petroglyphs and pictographs were the writing system of Hand Talk, a sign language that was the historically most spoken language on the continent, it is unknown to academia what, if any, connection there is between sign language and Suckerfish script. The gomgwejui'gasultijig take their name from the gomgwej (plural: gomgwejg) or sucker fish whose tracks are visibly left on the muddy river bottom. Mi'kmawi'sit uses several spelling systems, and the script is consequently sometimes called komqwejwi'kasikl or gomgwejui'gas'gl.
