Crasus Dome Õita is a retractable roof, multi-purpose stadium in the city of Ōita in Ōita Prefecture on Kyushu Island in Japan.

The stadium was built for Ōita Prefecture, which still owns it. Design was led by the famous architect Kisho Kurokawa and his firm Kisho Kurokawa Architect & Associates, and construction was carried out by a construction group led by the Takenaka Corporation. The stadium opened as Oita Stadium in May 2001.

In 2006 it was renamed Kyushu Oil Dome (九州石油ドーム, Kyūshū Sekiyu Dōmu), as a result of a sponsorship deal with Kyushu Oil. In early 2010, the stadium was renamed Õita Bank Dome (大分銀行ドーム, Ōita Ginkō Dōmu) when sponsorship shifted to Oita Bank. In early 2019, the stadium was renamed Showa Denko Dome Oita (昭和電工ドーム大分) after Showa Denko acquired naming rights. On 1 January 2023 Showa Denko merged with another company, forming Resonac Holdings Corporation.

Since January 2025, as a result of a sponsorship deal with Crasus Chemical Co., Ltd (a subsidiary of Resonac) the stadium is now called Crasus Dome Oita.

The stadium is primarily used for football and is the home field of J.League club Ōita Trinita.
