Alina Ilnazovna Zagitova (Russian: Алина Ильназовна Загитова, IPA: [ɐˈlʲinə zɐˈɡʲitəvə]; born 18 May 2002) is a Russian former competitive figure skater. She is the 2018 Olympic champion, the 2019 World champion, the 2018 European champion, 2017–18 Grand Prix Final champion, and the 2018 Russian national champion. She also won a silver medal in the team event at the 2018 Winter Olympics. Earlier in her career, she won gold at the 2017 World Junior Championships and at the 2016–17 Junior Grand Prix Final.

Having won all major International Skating Union (ISU) Championship titles at the junior and senior levels, Zagitova is the youngest and second women's singles skater, after Yuna Kim, to have completed a Super Slam. She is the second-youngest Olympic champion in women's single skating, behind Tara Lipinski. She holds the historical world record score in the women's short program. She was known for back-loading her programs, meaning she performed all jumps in the second half to receive a bonus on the jump's base value. This led to the ISU implementing a rule limiting the number of jumps that could receive the base value bonus, unofficially known as the "Zagitova rule".

During the 2019–20 season, Zagitova announced she would be taking a break from competitive figure skating, and as of 2025, has not returned to competition. Since then, she has co-hosted multiple seasons of the Channel One Russia show Ice Age and has done commentary and interviews at Russian figure skating competitions.

Zagitova was born on 18 May 2002 in Izhevsk, Udmurtia. She is the daughter of Leysan and Ilnaz Zagitov (ru), both Volga Tatars. Ilnaz Zagitov is an ice hockey coach from Tatarstan. Zagitova understands the Tatar language but does not speak it. She has a younger sister, Sabina, who was also a figure skater. She was nameless for a year until her parents decided to name her "Alina" after watching Russian rhythmic gymnast (and fellow Tatar) Alina Kabaeva.

When Zagitova was born, her father was playing hockey for the club Neftyanik Leninogorsk and taught her how to skate. The family moved to Almetyevsk when her father signed to play for Neftyanik Almetyevsk. Alina began skating at age four in Almetyevsk and was coached by Damira Pichugina. After the family moved back to Izhevsk, she started training with coach Natalia Antipina. She moved to Moscow at age 13 alongside her grandmother to train under Eteri Tutberidze.

Zagitova began learning triple jumps after moving to Moscow, but she broke her arm and then her leg. Eteri Tutberidze then kicked her out of her training group but decided to bring her back. In January 2016, Zagitova made her debut at the Russian Junior Championships and finished ninth. One month later, she finished fourth in the junior division at the 2016 Russian Cup Final.

Eteri Tutberidze and Daniil Gleikhengauz choreographed a short program to music from Samson and Delilah and a free skate to music from Don Quixote for Zagitova's first international season. She began performing all of her jumps in the second half of the program to earn bonus points on the base value, giving her a major technical advantage over her competitors.

Zagitova's international debut came in late August 2016 at the 2016–17 ISU Junior Grand Prix (JGP) competition in Saint-Gervais-les-Bains, France. She ranked first in both segments and won the gold medal ahead of Japan's Kaori Sakamoto. Her total score at the event, 194.37 points, was the second highest ever achieved by a women's single skater on the junior level, behind only Polina Tsurskaya. She then won the bronze medal at the JGP event in Slovenia, behind Japanese skaters Rika Kihira and Marin Honda. The results qualified her for the 2016–17 Junior Grand Prix Final, held in December in Marseille. There, Zagitova ranked first in both segments and won the gold medal with a total of 207.43 points, 13 points above silver medalist Anastasiia Gubanova. She became the first junior women's skater in history to have a total score above the 200 point mark.
