To'omata Lilomaiava Tua (10 July 1905 – February 1970) was a Western Samoan chief and politician.
He served as a member of the Legislative Assembly from 1951 and as Minister of Lands from 1959, holding both roles until his death in 1970.
Born in 1905, Tua was conferred with the chiefly title To'omata in 1924.
However, when a full cabinet system was introduced in 1959, he was appointed Minister of Lands.
His death deprived incumbent Prime Minister Fiame Mata'afa of a majority in a tied vote, and led to Tupua Tamasese Lealofi IV becoming prime minister.
