Lisa Whybourn (born 11 May 1991) is an English tennis player. Whybourn broke into the top 400 in the world in June 2010 following her run to the final qualifying round at Wimbledon. She is originally from Huntingdon, Cambridgeshire, but is now based at the Team Bath Tennis Academy in Bath, Somerset.
Lisa played her first junior ITF tournament in April 2006 and her last in the qualifying rounds for junior Wimbledon in June 2009. Over these three years she reached three singles finals (winning two of them) as well as three semifinals. She never passed the first round of junior Wimbledon and did not compete in any of the other three Grand Slam junior events. In doubles, she managed to win two titles. She was also a doubles runner-up twice and a semifinalist twice. Whybourn amassed a singles win-loss record of 31–22 and a win-loss record of 24–20 in doubles. Her career-high combined singles and doubles ranking was world No.177 which was achieved on 19 May 2008.
Lisa first competed on the ITF circuit in 2006 when she played two $10,000 events in Britain and lost in the qualifying rounds for each one. 2007 saw her compete in three more events worth $10,000 and again she lost in the qualifying stages. In 2008 she again competed in a number of lower-level ITF events and did not pass the first round in any of them.
Her first ITF semifinal came in September 2009 at the $10,000 event in Cumberland in London where she was beaten by Jade Windley, a fellow Brit. Immediately following this, she reached the second round of a $75,000 ITF in Shrewsbury before being beaten in straight sets by Elena Baltacha. After this she reached the quarterfinals of a $50,000 ITF event. Her very first year-end world ranking was No.531.
In April 2010, Whybourn reached the semifinals of a $10,000 event before going on to reach her first ever ITF final later that month where she was beaten by a Slovakian, Romana Tabakova. Another $10,000 ITF quarterfinal followed before Whybourn received a wild card into the qualifying draw for the Aegon Classic in Birmingham where she was beaten by Sophie Ferguson. She was then the recipient of another wild card, this one allowing her entry into Wimbledon qualifying. She beat Sally Peers and Anna Floris before being stopped in the final qualifying round by Andrea Hlaváčková. Returning to the ITF circuit for the rest of the season, Lisa reached two more quarterfinals and one more semifinal. Her year-end ranking was world No.333.
