The 2017 European Championships were held in Ostrava. Fernández skated a clean short program including two quads (one in combination with a triple), a triple Axel and all level four elements to claim first place in the segment and achieve a new personal best of 104.25 points. His free skate included three quads and seven triples, however he over-rotated his first quad Salchow and fell on the second. Fernández recovered to finish his routine and earned 190.59 points, winning the free skating segment over Russian Maxim Kovtun by over 18 points. Fernández received 294.84 points overall to win the gold medal, and became only the third men's skater to win five consecutive European titles, following Ondrej Nepela (1969–73), and Karl Schäfer, who won the title 8 consecutive times (1929–36).
