Daniela Álvarez Mendoza[a] (born 27 November 2001)[1] is a Spanish beach volleyball player.

She currently attends Texas Christian University where she is part of the TCU beach volleyball team.

Using the strength and coordination she developed as a tennis player, Álvarez played beach volleyball for just nine days before being invited to travel to the National Training Center.

Álvarez lived up to her accolades with the best record on the team from the Spring 2023 season, 37-1, and hit her 75th career win milestone.

She quickly lived up to these expectations when, for the second time in her career, was awarded both CCSA and AVCA Pair of the Week honors after season debuts (26–27 February).

1 position, with Team Spain partner, Tania Moreno Mateeva, the duo racked up 23 victories on the regular season with 11 over ranked opponents.
