Jonathan Franciscovich Guerreiro (Russian: Джонатан Францискович Гурейро;[1] born 3 April 1991) is a retired Australian-Russian ice dancer.

[4] After early partnerships with Australians Kiah Pilz and Rachael Reading, Guerreiro competed on the Russian regional level with Daria Panfilova.

At the end of the season, they switched coaches to Natalia Linichuk and Gennadi Karponossov, which required them to move to Aston, Pennsylvania in the United States.

[2] Prior to the 2013–14 season, Pushkash and Guerreiro began training with Anjelika Krylova and Pasquale Camerlengo in Bloomfield Hills, Michigan.

In 2014, Guerreiro formed a partnership with French ice dancer Tiffany Zahorski, coached by Alexander Zhulin.

The FFSG released Zahorski in October 2015, three years and nine months after her last competition for France, allowing Zahorski/Guerreiro to appear for Russia internationally.

In the 2016–17 season, Zahorski/Guerreiro won the bronze medal at the 2016 CS Ondrej Nepela Memorial after placing third in both segments and earning a new personal best total score of 165.64 points.

[10] In mid-May 2017 Zahorski/Guerreiro changed coaches to Elena Kustarova and Svetlana Alexeeva[11] Zahorski/Guerreiro started their season by winning the silver medal at the 2017 CS Minsk-Arena Ice Star.

It was announced by the Russian Figure Skating Federation on 23 January 2018 that Ivan Bukin was not invited to the 2018 Winter Olympics.

Zahorski suffered from a recurrence of a knee injury over the summer that limited the duo's training time leading up to the new season.

"[14] In early November Zahorski/Guerreiro competed at their second Grand Prix event of the season, the 2018 NHK Trophy, where they won the silver medal with a personal best score of 183.05 points.

[15] The team had major problems in the free dance, with Guerreiro's boot laces coming undone early on, and Zahorski making errors on both her twizzles and the one-foot step sequence.

[16] Zahorski tore the meniscus in her knee late in the summer, causing the team to lose significant training time.

[28] With the Grand Prix assigned based primarily on geographic location, Zahorski/Guerreiro competed at the 2020 Rostelecom Cup, coming second in the short program.

[30] Two-time defending national champions Sinitsina/Katsalapov sat out the 2021 Russian Championships, making Zahorski/Guerreiro the presumptive silver medalists behind Stepanova/Bukin.

[39] Returning to competition for the 2022 Russian Championships, Zahorski/Guerreiro were fourth in the rhythm dance, 4.60 points behind the newcomers Davis/Smolkin, a result which attracted audible boos from audience members in Saint Petersburg.

However, they struggled through the free dance, with Zahorski immediately going to the medical room upon leaving the ice, and dropped to eighth position overall.
