Introduction / History

The Mayo-Yessan Mayo in PNG are an indigenous people group living in the East Sepik and Sandaun provinces of Papua New Guinea, particularly in areas north of the middle Sepik River and in nearby hill regions. Their communities are part of a wider cluster of culturally related groups in the Sepik region, where geographic isolation has led to the development of distinct identities and languages over generations.

They speak the Yessan-Mayo language, a Papuan language associated with the Sepik linguistic region. This language is central to their identity and is shared among closely related neighboring groups, reflecting long-standing cultural connections while preserving local distinctiveness.


What Are Their Lives Like?

Life among the Mayo-Yessan Mayo centers on village communities where extended family and kinship relationships shape daily responsibilities and cooperation. The environment of hills, forests, and river systems provides the resources needed for daily living.

Most people depend on subsistence activities such as gardening, with staple crops forming the basis of their diet. The surrounding forests and rivers also provide additional food through hunting, fishing, and gathering. Community life is cooperative, with shared labor playing an important role in maintaining households and meeting needs.

Cultural traditions in the Sepik region often include ceremonial practices tied to agriculture and community identity. These traditions reflect long-standing patterns of life that have been passed down through generations.


What Are Their Beliefs?

The Mayo-Yessan Mayo are largely identified with Christianity, and the gospel has had a strong presence in their communities. Church life and Christian teaching play an important role in shaping values, relationships, and regular gatherings for worship. Most also have faith in the spirit world. The New Testament and portions of Scripture are available in the Yessan-Mayo language, providing an important foundation for personal faith.


What Are Their Needs?

There is a continuing need for deeper discipleship so that believers among the Mayo-Yessan Mayo are firmly grounded in Scripture and grow in spiritual maturity. Access to the full Bible in their language would further strengthen both individuals and the church community.

Equipping local leaders is essential so pastors and teachers can guide their communities with sound doctrine and wisdom. Strong leadership supports both spiritual growth and stability within village life.

Because many communities are in rural and sometimes remote regions, practical challenges such as limited access to education, transportation, and resources can affect both daily living and ministry opportunities. Addressing both spiritual and practical needs can help support long-term growth.


Prayer Items

Pray that the Mayo-Yessan Mayo believers will grow in a deep understanding of God's word and in obedience to Jesus Christ.
Pray for local church leaders to be equipped with sound doctrine and strengthened in their ministry.
Pray that families will be rooted in biblical truth and that younger generations will follow Christ with conviction.
Pray for increased access to Scripture, including the possibility of the full Bible in their language.
Pray for some to be called and sent to Muslims in Indonesia.
