Hindi Olympiad Foundation (HOF) is a Delhi Government-registered educational, social and non-profit organization dedicated to strengthening the Hindi language in India and internationally. Guided by educators and Hindi media specialists, it organizes an annual International Hindi Olympiad for students in classes 1 to 12. The competition gives students an opportunity to assess their Hindi knowledge and develop language skills, including grammar, spelling and written expression, while encouraging logical thinking, creativity and appreciation of Indian cultural values.

HOF supports students and schools with Olympiad information, grade-level syllabi, sample papers, registration and results. Its website also provides international and regional rankings, galleries and information about award ceremonies. To help students prepare and practise, the Foundation shares class-grouped Hindi grammar quizzes on Telegram twice a week, with leaderboards posted later in the day; a demo quiz is also available. Through these activities, HOF aims to make Hindi learning accessible and engaging, build students’ confidence and provide opportunities to measure their abilities at national and international levels.
