The Kinkaid School is a private PK–12 non-sectarian college preparatory school in Piney Point Village, Texas, United States in Greater Houston.

The Kinkaid School is the oldest independent coeducational school in Greater Houston. The student body is divided into the Lower School (PreK – 4th Grade), the Middle School (5th grade – 8th grade) and the Upper School (9th grade – 12th grade). The school motto is: "Lux per Scientiam" meaning, "Light through Knowledge". The School colors are purple and gold, and the school mascot is the falcon. The school is accredited by the Independent Schools Association of the Southwest.

The current head of school is Jonathan Eades. The current chairman of the Board of Trustees is Steven P. Mach.

A feature of Kinkaid's Upper School is its Interim Term, which provides three weeks in January for teacher-designed and student-selected curricula. Teachers at the School provide classes that they would otherwise not be able to teach as part of the normal semester, including military histories of the Civil War and World War II, introductory courses in digital programming and engineering, courses in photography and art history, and a course in Disney films. Students may also go on international trips sponsored by the school, such as tours of China, Italy and Greece; homestays in Mexico and France are also possibilities. Finally, the School provides connections with companies throughout the greater Houston area and, if the students prefer, throughout the world, in which its senior students may find internships.
