The 2026 Davis Cup Qualifiers first round took place from 5 to 8 February 2026, featuring 26 national teams competing in home-and-away ties for a coveted spot in the second round. The thirteen victorious nations advanced to the Qualifiers second round, while the thirteen losing teams were relegated to the 2026 Davis Cup World Group I. The field was determined by performances in the 2025 season, including six teams from the 2025 Finals (excluding champions Italy and runners-up Spain), seven losers from the 2025 Qualifiers second round, and thirteen winners from the 2025 World Group I. High-profile clashes included France vs. Slovakia, Canada vs. Brazil, Chile vs. Serbia, and Norway vs. Great Britain, with team rankings based on the 24 November 2025 standings. Ultimately, the winners earned the right to compete for a place in the Finals, while the losers faced a playoff to maintain their status in the competition.
