The second ticket was won in Bangui in March 2021, a 1–0 win over Central African Republic on the final day of qualifying. Cameroon 2021 was harder — three defeats, by The Gambia, Tunisia and Mali, without a goal — but it made Mauritania regulars rather than one-time visitors.
Côte d’Ivoire 2023 is the chapter that changed the story. After a stoppage-time penalty defeat by Burkina Faso and a 3–2 loss to Angola, Amir Abdou’s side needed to beat 2019 champions Algeria in Bouaké. Centre-back Yali Dellahi scored before half-time, goalkeeper Babacar Niasse held out through more than 11 minutes of stoppage time, and Mauritania had a first win at a finals and a place in the last 16, where Cape Verde beat them with an 88th-minute penalty.
Third place in their qualifying group, a point behind Botswana, kept Mauritania away from Morocco 2025. Spaniard Aritz López Garai, in charge since January 2025, now leads them into Group F with Burkina Faso, Benin and Central African Republic — the side they beat to reach Cameroon 2021. The top two qualify, and the campaign opens on 24 September 2026.
