Alexandra Margo Sholler (born 27 September 1984), better known as Alison Wonderland, is an Australian electronic dance music producer, DJ, and singer. Her debut album Run, released on 20 March 2015, peaked at No. 6 on the ARIA Albums Chart and was certified gold by ARIA. Her second album, Awake, debuted at No. 1 on Billboard's Top Dance/Electronic Albums chart. She was listed at No. 96 on DJ Mag's Top 100 DJs in October 2018. She is also the highest billed female DJ in Coachella history. Outside of being well known for her music, she is outspoken about her support for mental health and frequently shares her experiences with her fans.

Alison Wonderland was born as Alexandra Sholler in 1984. She is of Austrian and Croatian descent. She grew up in Sydney where she trained as a classical musician, specialising in cello. She performed as a cellist with the Sydney Youth Opera and was later a bass guitarist in a few local indie rock bands.

Wonderland later recalled how she developed an interest in electronic dance music, "I went out to a club called Candy's Apartment... Someone played 'Silent Shout' by the Knife... I remember just completely zoning out... and walking over to the DJ and asking, 'What is this track?! Please tell someone what this track is, because this is amazing'." Her performance name is a pun on the Lewis Carroll novel Alice in Wonderland.

During 2012 she worked as a remixer on Sam Sparro's "I Wish I Never Met You", which appeared as a bonus track on that artist's Japanese version of his second album, Return to Paradise (June 2012). Sneha Dave of Music Feeds observed, "[she] proves once again why she's becoming somewhat of a remix authority. Recently played by none other than Pete Tong on BBC Radio 1, [her] rendition perfectly complements Sparro's creamy vocals. Infused with a deep house sensibility, yet imprinted with original flair, this arrangement depicts exactly what a good remix should be – a tribute to the original."

Also in 2012 Wonderland toured with the Parklife Music Festival, visiting Australian city parks in September to October. Her set list included her remixes, Sparro's "I Wish I Never Met You" and Ladyhawke's "Blue Eyes (Alison Wonderland Remix)". Highlights were presented by Falcona on Vimeo, where she was also interviewed by the Bondi Hipsters. Purple Sneakers' Lauren Payne noticed, Wonderland's version of "Blue Eyes" is "a very digital remix of Ladyhawke's catchy new single. Swapping the guitar and drums for a more electronic vibe, [Wonderland] has make some techno tweaks to the single and the end product is, in true [Wonderland] style, just plain splendiferous!"

Alison Wonderland released her debut single, "Get Ready" (featuring Fishing), in July 2013. The track was co-written by Sholler with Russell Fitzgibbon, Brendan Picchio and Douglas Wright. Fitzgibbon and Wright perform as a house music duo, Fishing. She was signed to EMI Music Australia in 2014, which is part of Universal Music Australia. As a DJ, she embarked on a national tour playing in warehouses.

On 27 June 2014 her five-track debut extended play, Calm Down, was released. It provided two singles, "I Want U" (May) and "Cold". "I Want U", which was co-written by Sholler with Andrew Swanson (also known as Djemba Djemba), peaked at No. 38 on the ARIA Singles Chart, and was certified gold by ARIA in 2016. It topped the Hype Machine charts as her biggest hit to that time.

In February 2015, Wonderland released "U Don't Know" which featured Wayne Coyne from the Flaming Lips on guest vocals. The music video gained popularity due to Christopher Mintz-Plasse's lead role alongside Wonderland. "U Don't Know" peaked at No. 63 on the ARIA Singles Chart. In March, Wonderland released her debut studio album Run. For the album Wonderland used fellow Australian artists, Slumberjack and SAFIA as well as various producers, Djemba Djemba, Awe, and Lido. It peaked at No. 6 in Australia and No. 12 in New Zealand. K Spence from YourEDM.com praised the album due to its diversity and her involvement in the album, as she was credited as a writer, vocalist and producer. The title track was issued as a single on 11 June, along with its music video. The music video peaked at No. 6 in Australia which made it her biggest hit to date. "Run" had over two-million streams on Spotify as of 20 January 2016.
