At the Wuhan Open she lost in the first round to eventual champion Caroline Garcia. At the China Open she defeated Naomi Osaka again before losing to Alizé Cornet.

Having failed to qualify for the 2017 WTA Finals & losing both her round robin matches at 2017 WTA Elite Trophy, Kerber dropped out of top 20 for the first time since 2012.

On 16 November 2017, Kerber announced on Twitter that she had ended her partnership with longtime coach Torben Beltz and had hired Wim Fissette. Fissette would work with Kerber until 16 October of the following year.

Kerber started her season at Brisbane; her last entry into this tournament was in 2017. Her performance resulted in a shock first-round loss to Australian tennis player Samantha Stosur in straight sets, 7–6, 7–6. On January 12, before commencing the inaugural Adelaide International, she participated in an exhibition match alongside Simona Halep as part of the Rally for Resilience charity event, an effort to raise funds to aid the delivery of year-round sports program in socially-disadvantaged areas in South Australia.

A continually high-ranking left-handed female tennis player, Kerber has won 12 career singles titles across all surfaces on the WTA Tour, including the aforementioned three Grand Slam titles: the 2016 Australian Open, the 2016 US Open and the 2018 Wimbledon Championships.

Her advance to the finals combined with Serena Williams' loss in the semifinals to 10th seeded Karolína Plíšková meant that she gathered enough points to successfully unseat Serena Williams as world No. 1, with this ranking reflected in the week starting 12 September 2016. She defeated Plíšková in three sets in the final to claim her second Grand Slam title.

On 17 October 2016, Serena Williams pulled out of the WTA Finals in Singapore due to a shoulder injury.
