OK Liga Femenina is a Spanish rink hockey league for women. It has been held since 2008 and is the women's version of the men's OK Liga.

Roller hockey, rink hockey or quad hockey is a team sport played on roller skates. It is a quad-skate team sport where two teams face-off against one another, trying to drive a hard ball with their sticks into the opposing teams' goalnet. Each team has five players on the rink at a time, four of whom are skaters and one who is the goalkeeper. The ball can only be put in motion by a stick, not the skate, otherwise a foul will be stated. The game has two 25-minute halves, with 15-minute halftime intermission, plus up to two 5-minute golden goal periods to settle ties with the clock stopping when the ball becomes dead. If the tie persists, a penalty shootout will determine the winner. Players – including the goalie – use quad skates, whereas inline skates are used in inline hockey. The sticks are similar to those in bandy and shinty. Excessive contact between players is forbidden in rink hockey, unlike inline hockey.
