Johanna Basford OBE (born 1983) is a Scottish illustrator. Her illustrations are hand-drawn, predominantly in black and white, with pencils and pens, and can be found in products such as colouring books, wallpaper, beer labels and tattoos. She has published colouring books for adults.

Basford was born in 1983 in Scotland and grew up on her parents' fish farm in Auchnagatt in Aberdeenshire. After attending Ellon Academy, she graduated from Duncan of Jordanstone College of Art and Design (DJCAD) in Dundee in 2005 with a degree in textile design and a specialisation in screen printing.

Previously married to James Watt, the co-founder of BrewDog, together they had two daughters. In February 2021, she announced she had separated from her husband the previous year.

Basford lives and works in Aberdeenshire, Scotland, where she owns a studio in a converted farmhouse.

Basford believes computer generated graphics can feel "cold and soulless", which is why she uses traditional media.

Since publishing her first adult colouring book Secret Garden in 2013, she has sold more than 21 million books worldwide.

She was appointed Officer of the Order of the British Empire (OBE) in the 2016 Birthday Honours for services to art and entrepreneurship.

In 2019 she broke the Guinness World Record for the Largest Drawing by an Individual, creating a floral drawing over 501 square metres (5,390 sq ft) in twelve hours at her former school, Ellon Academy.
