Acquire Corp. (株式会社アクワイア, Kabushikigaisha Akuwaia) is a Japanese video game developer and publisher, mainly known for their Tenchu and Way of the Samurai series.

Acquire was founded on December 6, 1994, and in 1998 developed Tenchu: Stealth Assassins for the PlayStation, which turned into a franchise. The developer pushed for a more sandbox approach to the level design, which found its way in other Acquire titles like Way of the Samurai and Shinobido: Way of the Ninja.

In 2011, the company was acquired by GungHo Online Entertainment. Acquire co-developed Octopath Traveler with Square Enix, releasing in 2018. Acquire was chosen as development partner for the game based on their affinity with pixel-art and prior work on the What Did I Do to Deserve This, My Lord? series. Acquire developed Katana Kami: A Way of the Samurai Story, which released in 2020, following the cancellation of a fifth Way of the Samurai entry.

In 2024, the company was acquired by Kadokawa Corporation.
