Kamnoetvidya Science Academy (Thai: โรงเรียนกำเนิดวิทย์, RTGS: Rongrian Kamnoet Wit; also known colloquially as KVIS) is a high school in Thailand. The school uses a customised curriculum mainly focused on mathematics, science, engineering and technology. Native English speakers are employed to teach English as well as other subjects. Apart from English, various other languages which are Chinese, Korean, Japanese, Spanish, German and French are taught to students.

Kamnoetvidya Science Academy, with the former name of Rayong Science Academy (RASA), was founded in 2013. The name Kamnoetvidya, which literally means “The Genesis of Knowledge”, was given by Princess Maha Chakri Sirindhorn on 6 August 2015 presided over the grand opening ceremony of the school. Kamnoetvidya Science Academy is supported by the Power of Learning foundation with an endowment fund provided by the PTT Public Company Limited to ensure sustainability, prosperity, and longevity of the academy. The conception of Kamnoetvidya Science Academy was the result of a farsighted vision and a cumulated passion of Dr. Pailin Chuchottaworn, then the chief executive officer and president of PTT Public Company Limited, who wishes to see Thailand emerge as a strong power in science and technology. Dr. Thongchai Chewprecha, the founding principal, retired from his position in 2018 and currently, he is succeeded by Dr. Rachain Kosanlavit. Currently, Dr. Boonchoat Paosawatyanyong is the principal of the school. Meanwhile, Dr. Thongchai continues to contribute as Principal Emeritus.
