The home field advantage in the 2025 National League Championship Series (NLCS) depends on the outcome of the Milwaukee Brewers vs. Chicago Cubs Division Series. If the Milwaukee Brewers defeat the Cubs, the Brewers will have home field advantage in the NLCS. If the Chicago Cubs win the series, then the Los Angeles Dodgers will have home field advantage when they face the Cubs. The Brewers hold the top seed in the National League with the best regular-season record (97-65), followed by the Cubs and the Dodgers, so the higher seed among the advancing teams hosts the NLCS games with home field advantage.
