Nikkie de Jager, better known by her YouTube channel name NikkieTutorials, is a Dutch makeup artist and beauty vlogger. She gained online popularity in 2015 after her YouTube video, "The Power of Makeup", went viral and inspired many other videos of people showing their faces with and without makeup. As of October 2019, her YouTube channel has 12.4 million subscribers and over 1.1 billion video views.

De Jager first began uploading videos to YouTube in 2008, at the age of 14, after watching MTV's The Hills while sick and being inspired by Lauren Conrad's makeup. While searching YouTube for tutorials to recreate the look, she was inspired to begin creating her own. After uploading videos for about two years, she enrolled in makeup coursework at B Academy in Amsterdam. She then signed to Colourfool Agency in 2011, and began working as a professional makeup artist.

In the fall of 2013, she became the head makeup artist for RTL5's show "I Can Make You a Supermodel" with Paul Fisher. De Jager left Colourfool Agency at the beginning of 2014 to work as a freelance hair and makeup artist.

Forbes magazine named De Jager one of the top ten beauty "influencers" in 2017. That same year, she also won the award for "YouTube Guru" at the Shorty Awards and the award for "Choice Fashion/Beauty Web Star" at the Teen Choice Awards.

In January 2019, it was announced that De Jager would serve as the Global Beauty Adviser for Marc Jacobs Beauty. The brand stated in a press release "In this newly created role, Nikkie will be integrated into the brand’s product development process, as well as share her incredible talent and expertise to expand unique content and artistry around the world on both Marc Jacobs beauty and her own channels."

De Jager has also collaborated with beauty brands Ofra, and Maybelline. Her line with Ofra included liquid lipsticks and a highlighter palette. In December 2019, she collaborated with Lady Gaga, promoting and giving away her makeup brand Haus Labs.

On January 13, 2020, de Jager uploaded a video to her YouTube channel, titled "I'm Coming Out.", in which she revealed that she is transgender and underwent her transition in her late teens.
