División de Honor Femenina de Balonmano or Liga Guerreras Iberdrola, named after the sponsorship of Iberdrola, is the premier women's professional handball league in Spain, administered by the Royal Spanish Handball Federation (RFEBM).

The 4 last ranked teams are relegated to División de Honor Oro Femenina, a league newly created for the 2022-2023 season.

Balonmano Sagunto, formerly known as Medina, Íber, and Mar Valencia, is the championship's most successful club with 27 titles, having dominated the competition throughout the 1980s and most of the 1990s, while SD Itxako has become its major team in recent years, ending the hegemony of Valencian clubs for the past three decades.

This means that, like its counterparts in Liga ASOBAL, each División de Honor season ends after every team plays 26 matches.

[citation needed] Like many other leagues in continental Europe, the División de Honor takes a winter break once each team has played half its schedule.
