Momase Region is one of four regions of Papua New Guinea. Its largest city is Lae, the second city of the nation. The name Momase is a portmanteau of the constituent provinces, Morobe, Madang and Sepik (East and West). Momase is by far the most linguistically diverse region of Papua New Guinea.{{cite web |url=https://www.ethnologue.com/country/PG/languages |title=Papua New Guinea languages |work=Ethnologue: Languages of the World |edition=22nd |editor1-last=Eberhard |editor1-first=David M. |editor2-last=Simons |editor2-first=Gary F. |editor3-last=Fennig |editor3-first=Charles D. |date=2019 |location=Dallas |publisher=SIL International}}
