In January it was announced that Mustafina would compete at the Stuttgart World Cup in early March. It was the first time she competed in the all-around in international competition since the Rio Olympics. In March, at the Russian National Championships, Mustafina finished third in the all-around behind Angelina Simakova and Angelina Melnikova. At the Stuttgart World Cup Mustafina finished in fifth place after falling off the balance beam. The following week Mustafina competed at the Birmingham World Cup where she finished first despite falling off the balance beam. After a winning in Birmingham, Mustafina was named to the team to compete at the 2019 European Championships, replacing national champion Simakova who had inconsistent performances in Stuttgart earlier in the month. In April it was announced that Mustafina had withdrawn from the European Championships team in order to focus on preparing for the European Games in June.
