Katrina Elizabeth Leskanich (/lɛˈskɑːnɪtʃ/ leh-SKAH-nitch; born April 10, 1960) is an American musician and the former lead singer of the pop rock band Katrina and the Waves. Their song "Walking on Sunshine" was an international hit in 1985. In 1997, the band won the Eurovision Song Contest for the United Kingdom with the song "Love Shine a Light". Both of those songs were written by her long-term bandmate Kimberly Rew.

After the Waves broke up in 1999, Leskanich launched a solo career. She released her first solo CD, Katrina Leskanich, through Universal Records in Britain in 2005.

In February 2005, Leskanich participated in the Melodifestivalen 2005 which is the pre-selection for Sweden's Eurovision Song Contest entry. She did a duet with the band 'The Nameless' in the 4th semi final. Their song 'As If Tomorrow Will Never Come' came 3rd in the semi-final, progressing to the Second Chance round where they came 6th and did not qualify for the final.

In 2005, Leskanich reflected on sharing her name with a hurricane that devastated the U.S. Gulf Coast in late August and early September of that year, after the name "Katrina and the Waves" appeared on numerous news television shows, headlines, and blog postings that were covering her namesake hurricane. When a New York Times reporter contacted her about this, she said: "The first time I opened the paper and saw 'Katrina kills 9,' it was a bit of a shock. ... I hope that the true spirit of 'Walking on Sunshine' will prevail. I would hate for the title to be tinged with sadness, and I will have to do my own part to help turn that around." She also stated that she hoped that "Walking on Sunshine" would become an anthem for the Gulf Coast's recovery.

To celebrate the 25th Anniversary of "Walking on Sunshine", Leskanich released her first live album The Live Album, in July 2010. The album includes both a live version and a blues version of "Walking on Sunshine". "I have performed 'Walking on Sunshine' for so many years in so many different countries that it's become the one constant in my life and the one thing I can count on to bring happiness to myself and others," said Leskanich. As part of the 25th Anniversary celebrations, Leskanich also performed 'Walking on Sunshine' on GMTV.

In September 2010, Leskanich re-released her solo album Turn The Tide with two bonus tracks: the club mix of "They Don't Know" and the Espirito mix of "Walking on Sunshine". In May 2011, Leskanich released an EP entitled Spiritualize. "In 1999 I wrote, collected and compiled some songs I thought would come together for an uplifting and spiritual type of album. I thought I'd try to make this a bit more personal," said Leskanich.

In 2013, Leskanich and her new band performed at festivals in the UK and Europe, including the San Fermín festival in Pamplona in Spain on Plaza del Castillo, and the Steinegg Festival in Italy. In 2014, Leskanich, a firm believer in animal rights, supported Wildlife Rocks with an acoustic performance. Other performers included Queen lead guitarist and founder of the Save Me organization, Brian May. The event raised awareness for vital wildlife projects, and was attended by several members of Parliament.Year end saw Leskanich perform on Hubei TV's Global New Year Revelry in Beijing

Leskanich released her second solo album, Blisland, which was inspired by the genre of music from her formative years. "I wanted to record an album that reflected my love of all the genres of music I grew up listening to, from Peter Frampton Live (sic) to Neil Young's Harvest. I fell in love with the South West of England; the beautiful beaches reminded me of California, and a little village called Blisland not only had a fantastic little pub but also gave me the perfect name for my new album."

In the Summer of 2014 Leskanich performed at many UK and European festivals including Festival Too in Norfolk, Guilfest in Surrey, Audley End in Essex, Nostalgie Beach Festival in Belgium and the Flashback Festival at Clumber Park in Nottinghamshire.
