Map - Gaga'emauga (Gaga‘emauga)

Gagaemauga is a district on the island of Savaii in Samoa. The district is situated on the central north side of Savaii. The name 'Gagaemauga' literally means "near side of the mountain", meaning the eastern side of the mountain chain running through the centre of Savaii Island.

The traditional centre of the district is Saleaula, where the district chiefs (matai) and orators meet at Vaituutuu malae.

Like most villages in Samoa, the villages in Gagaemauga are situated by the sea although there are some settlements inland, including Patamea and Samalaeulu.

Reverend George Pratt (1817–1894), a missionary with the London Missionary Society, lived in Matautu (1839–1879) and authored the first grammar and dictionary of the Samoan language, "A Grammar and Dictionary of the Samoan Language, with English and Samoan Vocabulary", which was first printed in 1862 at the Samoa Mission Press.

The village of Saleaula maintains strong traditional connections with Safotulafai to the east, through the paramount chiefly title of Letufuga. Safotulafai is the capital of the political district Fa'asaleleaga.

Two small exclaves of Gaga'emauga district are situated on the island of Upolu, following the resettlement of villages destroyed during volcanic eruptions of Mt Matavanu in the early 1900s. These exclaves are Le'auva'a and Salamumu villages which remain politically part of Savai'i despite their relocation.
