2021–22 Real Madrid CF season

The 2021–22 Real Madrid Club de Fútbol season was the 118th season in existence and the club's 91st consecutive season in the top flight of Spanish football. In addition to the domestic league, Real Madrid participated in this season's editions of the Copa del Rey, the Supercopa de España, and the UEFA Champions League.

This season saw Carlo Ancelotti return to the club, having led it to La Décima in his first spell. On the domestic front, he delivered two trophies out of possible three, winning La Liga and the Supercopa de España. With that, Ancelotti became the first manager in Real Madrid history to have won all of the six available top-tier major trophies. In the Champions League, Madrid produced one of the most memorable runs of all time, defeating pre-tournament favorites Paris Saint-Germain, defending champions and favorites Chelsea, Premier League champions and heavy favorites Manchester City, all in dramatic fashion, and setting up the final against Liverpool, who were once again widely considered as favorites, in a rematch of their 2018 encounter. A lone Vinícius goal in the second half sealed the 14th European Cup for Los Blancos, their fifth in nine years. This was also Carlo Ancelotti's fourth Champions League title as coach, making him the most successful manager in the competition's history. Real also claimed their fourth ever European double (after 1956–57, 1957–58, and 2016–17).

This was the first ever season since 2004–05 without former captain Sergio Ramos, who departed for Paris Saint-Germain in the summer and first time since 2010–11 without the Frenchman Raphaël Varane who departed to Manchester United, with both having been Madrid's first choice centre-back pairing for years, therefore leaving in the same transfer window.
