At the
2006 Australian Open, Mauresmo captured her first
Grand Slam singles title, defeating Belgian former world number one players
Kim Clijsters and
Justine Henin-Hardenne en route. Both opponents retired from their respective matches, Clijsters with a right ankle sprain in the third set of their semifinal and Henin from gastroenteritis in the final. Mauresmo was leading in both matches — by 6-1, 2-0 against Henin-Hardenne.
Mauresmo then won her next two tournaments, the
Open Gaz de France tournament in
Paris (defeating Pierce in the final) and the
Proximus Diamond Games in
Antwerp (defeating Clijsters in the final).
In the
Qatar Total Open in
Doha, Mauresmo defeated
Martina Hingis in a semifinal 6-2, 6-2 but lost to
Nadia Petrova in the final 6-3, 7-5. Had she won the final, she would have immediately regained the No. 1 ranking from Clijsters. Nonetheless, the outcome was sufficient to ensure Mauresmo's return to the No. 1 ranking on
March 20, 2006. This reflected the fact that neither Mauresmo nor Clijsters participated in the 2006
Pacific Life Open in
Indian Wells, California. Thus, neither defended her ranking points from the 2005 tournament, which Clijsters won.
Mauresmo then reached the semifinals of the
Sony Ericsson Open in
Key Biscayne, Florida, where she lost to the eventual champion
Svetlana Kuznetsova.
Though now a Grand Slam champion and the top ranked player in the world, Mauresmo once again succumbed to the weight of national expectations at the
French Open, losing to
Czech teen
Nicole Vaidišová 6-7(5-7), 6-1, 6-2 in the fourth round in front of a packed
Court Philippe Chatrier crowd.
Mauresmo next suffered a first round loss at the
Wimbledon warm-up event in
Eastbourne. Mauresmo and Kuznetsova won the doubles title there, which was their first as a team and Mauresmo's second overall.
Mauresmo was the top seed at
Wimbledon. She defeated Anastasia Myskina in the quarter-final and [Maria Sharapova]] in a semifinal and then came back from a first set blowout to defeat Henin-Hardenne in the final 2-6, 6-3, 6-4. The victory was Mauresmo's second Grand Slam singles title and first title on grass. She was also the first French woman since Suzanne Lenglen to win Wimbledon.
She then pulled out of the
Fed Cup World Group I playoff tie against the Czech Republic due to a groin injury sustained during Wimbledon. She also withdrew from the
Rogers Cup in
Montréal.
Her next tournament was the
Pilot Pen Tennis tournament in
New Haven, Connecticut, where she lost in the quarterfinals to
Lindsay Davenport 6-4, 7-5.
At the
2006 U.S. Open, Mauresmo lost to Sharapova in a semifinal 6-0, 4-6, 6-0. It was the first time in the
open era that a female semifinalist here lost two sets at love.

Mauresmo then reached the final of the
China Open, losing to Kuznetsova 6-4, 6-0. During the tournament, Mauresmo won 137 ranking points to help preserve her World No. 1 ranking and ended a nine match losing streak to Davenport. The last time Mauresmo had defeated Davenport was in
Sydney in January 2000.
To conclude the year, Mauresmo reached the final of the
WTA Tour Championships in
Madrid, losing to Henin and finishing the year ranked No. 3 behind Henin and Sharapova.
