Jonalyn Roxas Viray, known mononymously as Jona, is a Filipino singer. She was catapulted to mainstream prominence after she emerged as the first grand champion of Pinoy Pop Superstar.
She was the lead singer of trio girl-group La Diva, alongside Maricris Garcia and Aicelle Santos following her career as a solo artist. They were chosen to sing the Philippine National Anthem at the Manny Pacquiao vs. Miguel Cotto boxing match in Las Vegas as well as the theme song of Philippine remake of the Mexican telenovela, Rosalinda. Following the group's disbandment and her return as a solo artist, she released her single "Help Me Get Over" which was awarded the Song of the Year Award at the 6th PMPC Star Awards for Music. Jona ended her decade-long exclusivity with GMA in February 2016 and transferred to ABS-CBN, changing her screen name to Jona.
