Faleasi'u is one of the largest village settlements on the island of Upolu in Samoa.

[2] Faleasi'u consists of five sub-villages pito nu'u: Safee, Sapulu, Lealalii, Moamoa, and Tauo'o.

The Samoan historian Teo Tuvale (1855–1919) was born in Faleasiu.

Tuvale's father, Vaaelua Petaia (1822–1881) was the first pastor in the village.

Petaia was one of the first Samoan Christian converts to the London Missionary Society and an early student at Malua Theological College.
