Riya Thiyagarajan (full name Nagapriya Riya Thiyagarajan) is a Tamil model, social media influencer, and Bigg Boss Tamil critic from Chennai, Tamil Nadu. She built her online presence through her commentary and reviews of Bigg Boss Tamil seasons on social media, becoming a familiar face among Tamil reality TV audiences before she herself became a contestant. She finished as the Second Runner-Up at the Miss Chennai 2023 beauty pageant. She is not to be confused with VJ Vishal's ex-girlfriend Riya Vishwanathan — a distinction that was widely clarified when her entry into the Bigg Boss house was announced. In November 2024, she entered Bigg Boss Tamil Season 8 as a wildcard contestant on Day 28. She was evicted in Week 6 (Day 42), finishing 20th overall.
