Katarina Sonja Rodriguez (Tagalog pronunciation: [ɾoˈdɾigɛs]; born August 1, 1992) is a Filipino actress, athlete, model and beauty pageant titleholder who was crowned Miss World Philippines 2018. She represented the Philippines at the Miss World 2018 pageant but was unplaced. Previously, she was crowned Binibining Pilipinas Intercontinental 2017 and placed 1st Runner-Up in Miss Intercontinental 2017.

She rose to fame after being the last eliminated in the second season of Asia's Next Top Model in 2014.

Rodriguez was born in Orlando, Florida, United States, to Filipino parents. Her mother is from Manila, while her dad is from Davao. She spent her childhood going back and forth the United States and the Philippines every other year.

She attended high school in Orlando and recounted the bullying she experienced at school, which would later on help her develop "tough skin" before finally moving permanently to the Philippines with her family. In Manila, she pursued and completed a double major in business management and philosophy from the De La Salle University.

She is also a cycling instructor, a competitive long-distance runner, and participated as a member of the De La Salle University Women's Track and Field Team.

At the encouragement of her two close friends, Katarina auditioned for the second season of Asia's Next Top Model. She was selected as part of the show's final three contestants along with fellow Filipina candidate Jodilly Pendre, finishing as a runner-up.

After her appearance in Asia's Next Top Model, Rodriguez caught the attention of well-known beauty queen trainer, Jonas Gaffud of Aces and Queens, who encouraged her to try out pageantry.

Rodriguez joined the Binibining Pilipinas 2017 pageant and won the title of Binibining Pilipinas Intercontinental 2017 during the coronation night held at the Smart Araneta Coliseum on April 30, 2017, gaining her the right to represent the Philippines at Miss Intercontinental 2017.
