Koa

In traditional Hawaiian society, koa referred specifically to members of the warrior class who served under the aliʻi.

Hawaiian oral histories recorded by Samuel Kamakau and David Malo in the 19th century describe the training and customs of the koa, whose duties included protection of chiefly households and participation in the interisland wars that preceded the

unification of the islands under Kamehameha I, completed in 1810.

The Acacia koa tree itself holds ecological and cultural weight as the second-most common tree in Hawaiian forests.

Koa wood, prized for its acoustic properties, became central to the construction of Hawaiian ukuleles and slack-key guitars after the introduction of European stringed instruments in the 1880s.

The renaissance of Hawaiian cultural identity during the 1970s brought renewed attention to the word and its associated crafts.

Koa first appeared in the U.S. SSA top 1000 for boys in 2015 and has climbed steadily, reaching roughly number 520 by 2023.

Use is strongest in Hawaiʻi, California, Oregon, Washington, and Colorado, where Pacific cultural influence and interest in short, nature-rooted names intersect.

The name is also rising in New Zealand, where Polynesian heritage names are increasingly chosen beyond Māori communities.

Contemporary bearers include the son of retired NFL quarterback Mark Sanchez and several children of surfers and musicians connected to Hawaiʻi.
