Oki Rengga Winata (born June 26, 1990) is an Indonesian stand-up comedian, actor, and former football player. He joined the Stand Up Indo Medan community in 2015. His name became widely known as a comedian after participating in the third season of Stand Up Comedy Academy, a competition held by Indosiar in 2017. A year later, he became the runner-up in the eighth season of Stand Up Comedy Indonesia on Kompas TV.

Oki started his career as a football player by enrolling in a football school in Langkat. Initially, he played as a defender, but due to stamina issues, he was moved to the goalkeeper position.

Oki ventured into stand-up comedy after joining Stand Up Indo Medan. At first, he was just a spectator. However, when the community held a competition, he decided to participate and ended up winning first place. From then on, he began practicing regularly with the community in between his football competitions. His comedic material often revolved around his experiences as a football player in Indonesia, particularly as a goalkeeper. Even when he moved to Palangka Raya to play for Kalteng Putra in 2016, he continued practicing with the Stand Up Indo Palangka Raya community whenever he had free time. Besides training, he frequently performed at local, regional, and intercity stand-up comedy events.

In 2017, Oki auditioned for Stand Up Comedy Academy in Medan and qualified as one of the top 35 finalists in its third season. However, he was eliminated in the top 20 round before stepping away from the microphone.

In 2018, Oki joined the eighth season of Stand Up Comedy Indonesia on Kompas TV. He auditioned in Jakarta, earned a golden ticket, and successfully advanced as a finalist. Under the new competition format, Oki was placed in Cak Lontong’s team alongside fellow contestants Haris Teguh, Yudha Ilham, Nur Arifin Ipin, and Bintang Bete. Staying consistent with his football-related material, Oki steadily progressed through the competition, even eliminating some of the top favorites. His breakthrough moment came when he defeated senior comedian Bintang Bete in the top three round, securing a place in the grand final. Despite delivering a strong performance, he ultimately finished as the runner-up.

Oki is the first football player in Indonesia to transition into a stand-up comedian.
