Over the last few years, the 30-year-old has struggled with a severe knee ailment, and his ranking has dropped to 113. With a post headed "Grateful," Konta announced the news on social media.
Konta Twitted: "This is the word that I've probably been used to the most during my career, and is the word that I feel explains it best at the end. My playing career has come to an end, and I am so incredibly grateful for the career that it turned out to be. All the evidence pointed towards me not "making" it in this profession. However, my luck materialized in the people that came into my life and impacted my existence in ways that transcended tennis. I am so incredibly grateful for these people. You know who you are. Through my own resilience and through the guidance of others, I got to live my dreams. I got to become what I wanted and said as a child. How incredibly fortunate I count myself to be. How grateful I am."
Konta was born in Australia to Hungarian parents and went to Europe as a teenager to pursue her tennis career, settling in Eastbourne with her family and acquiring a British citizen in 2012. Konta's ascension to the top of the game began when she won the British No. 1 ranking, which she held for over six years. The next year, at the Australian Open, she made her maiden Grand Slam semi-final and climbed into the top ten.
In 2017, she became the first British player to reach the Wimbledon semi-finals since Virginia Wade, won the biggest of her four career championships at the Miami Open, and peaked at fourth in the world rankings. Konta fell out of the top 100 in 2018 but rebounded the following year, reaching another Grand Slam semi-final at the French Open and quarter-finals at Wimbledon and the US Open.
Scott Lloyd, chief executive of the Lawn Tennis Association, said: "On behalf of the LTA and everyone involved in British Tennis I want to express my appreciation to Johanna for her hugely impressive career. To reach the semi-finals of three slams and spend more time as British number one than any other woman since the WTA rankings began shows the level of her achievements. We wish her well in the future, and hope that she will continue to play a role in British tennis in the years to come."
Iain Bates, LTA head of women's tennis, said: "Johanna is a tremendous inspiration for so many in British Tennis, and everyone at the LTA and involved in the sport is immensely proud of what she has achieved. It has been a great privilege for me personally to watch her evolve into the player she became. She leaves a legacy of perseverance, determination and professionalism that will be carried forward by the current and next group of players."
Konta is set to marry fiance Jackson Wade in the near future and has made no secret of her desire to create a family, something she didn't want to do while pursuing her career. She will be remembered as the best British female player of the last 30 years, and for their professionalism and dedication.
