Sienna Tandon

On July 19, 2026, Sienna Tandon, 17, of Johnston, Rhode Island, was crowned Miss Rhode Island Teen USA 2026. A senior at Wheeler High School, Sienna is passionate about academics, leadership, and service. She is trilingual, speaking English, Spanish, and Mandarin Chinese, and is proud to be the first Miss Rhode Island Teen USA of Guatemalan and Indian heritage.

Sienna’s journey is rooted in her belief that everyone deserves to feel valued, confident, and celebrated. Raised by a hardworking mother, she has always admired her mother’s resilience, determination, and selflessness. Watching her mother overcome challenges while providing endless love and support inspired Sienna to pursue her dreams with confidence and gratitude. She gives credit to her family for encouraging her to step outside her comfort zone and compete in this pageant, her very first pageant; she is so glad she listened!

Inspired by her family’s experiences and her passion for educational equity, Sienna founded Supplies for Smiles, a nonprofit dedicated to providing students with the school supplies and educational resources they need to succeed. She believes every child deserves the opportunity to learn and thrive, regardless of their financial circumstances; she is committed to helping remove barriers to education.

Beyond her community involvement, Sienna enjoys spending time with her family and friends, traveling, and embracing new cultures. She believes her multicultural background has shaped her perspective and strengthened her commitment to promoting equality, celebrating diversity, and encouraging others to embrace what makes them unique. Although this was Sienna’s first pageant, she never imagined walking away with the title. The experience introduced her to lifelong friendships and reminded her that pageantry is about much more than a crown – it’s about uplifting others, celebrating authenticity, and using your voice to create positive change. As Miss Rhode Island Teen USA 2026, Sienna is honored to represent Johnston and the Ocean State at Miss Teen USA and hopes to inspire others to embrace their heritage, serve their communities, and believe that their background is one of their greatest strengths.
