Ma. Ahtisa Manalo (মা. আহতিসা মানালো) is a Filipino model and beauty pageant titleholder who was crowned Miss Universe Philippines 2025. She represented the Philippines at the Miss Universe 2025 pageant, where she placed as the third runner-up.

Manalo previously represented the Philippines at Miss International 2018, where she placed as first runner-up. She later represented Quezon in the Miss Universe Philippines pageant in both 2024 and 2025. In the 2024 edition, she placed as second runner-up and was subsequently appointed to represent the Philippines at Miss Cosmo 2024, where she finished in the Top 10.

Manalo was born on May 25, 1997, in Candelaria, Quezon, to a Filipino-Spanish mother and a Finnish-Swedish father. She was named after her biological father, Ahti, from whom she has remained estranged. She was raised by her grandmother with financial support from her godfather for her education. Manalo initially intended to become a police officer and applied to the Philippine National Police Academy. She later pursued a degree in accountancy at the Manuel S. Enverga University Foundation.

Manalo is involved in the café business, managing two establishments in Australia—Cafe Noun and Call Me Harris. She has also played a key role in the creation and expansion of food brands such as Koomi, Oh My Greek, and Zig Foods, with locations in her home province of Quezon, across the Philippines, and internationally.

On October 9, 2024, Manalo filed her candidacy to run for a seat in the Candelaria Municipal Council in 2025, running as an independent under the slate of incumbent mayor Ogie Suayan. She later withdrew from the race after being reappointed as the local Miss Universe Philippines titleholder for Quezon.

Manalo is often referred to in the media as the pambansang manika (lit. 'national doll'), owing to her doll-like features. Leading up to Miss International 2018, pageant analysts noted that she possessed "the beauty, charm, demeanor, and physique" ideal for success in the competition.

Manalo identifies as an ally of the LGBTQIA+ community and an advocate for gender equality. She is also involved with Alon Akademie, an organization that focuses on developing children's global citizenship, social skills, and entrepreneurial mindset.

In an interview with Boy Abunda, which aired on May 7, 2025, Manalo confirmed that she is single. She shared that she prefers to "wait for the right person rather than actively searching for a relationship." She also highlighted the importance of self-worth, stating that any future partner must bring something meaningful to her already fulfilling life.
