OKASHII (おかしい) is a South Korean hip-hop group formed in 2018, from AP Alchemy, Minefield record label. Jeffrey White, Raf Sandou, Mason Home and Matt are the current artists under the crew.

The group is known for blending elements of hip-hop and R&B. With a unique style that has garnered a strong fanbase in the Korean underground music scene. The crew's name OKASHII has Japanese origins, meaning “weird” or “strange” which reflects their avant-garde approach to music and performance.

OKASHII originally emerged from the RYU hip-hop club at Yonsei University, one of Korea's top universities. The members of the crew including Jeffrey White and Raf Sandou , were part of this club during their college years, overtime, the crew expanded and evolved, attracting attention from the broader Korean hip-hop community. The group's connections to Yonsei University gave them a unique platform, and several of the members have pursued careers in different artistic fields including, photography and music production.
Several other former members and collaborators contributed to the group's legacy, including photographers like Heidi and musicians like Cold Bay, although some of them then have since moved on to different paths.

OKASHII's sound combines raw, emotional lyricism with experimental beats. Their music is often described as a mix of underground hip-hop with R&B, characterized by smooth flows, deep introspection, and an emphasis on storytelling. Their lyrics often address themes of identity, self-exploration, and societal critique, aligning with the broader messages of modern Korean hip-hop.
