The Swiss Women's Basketball Championship, or SB League Women, is the highest tier level of women's professional club basketball competition in Switzerland. The league is also sometimes referred to as National League A (NLA or LNA). Currently the SB League Women is granted one spot in the FIBA EuroCup Women.
The 2019–20 season ended prematurely due to the coronavirus pandemic in Switzerland and in March 2020 the Swiss Basketball Executive Committee announced that no team would be awarded the national championship title.
