Princess Nikki is a reality television show that stars former Big Brother 7 UK house mate, Nikki Grahame. It ran on Wednesday nights between 10:00 - 10:30pm on the digital television channel E4 from 6 September 2006, for a total runtime of 30 minutes. The show was devised by Endemol, the company that also devised Big Brother. It was narrated by the presenter and comedian, Alex Zane.

The format saw Nikki attempt several jobs on each show, which included various unpleasant tasks such as rubbish collecting, deep sea fishing, and waste management. The show's premise was to see whether or not Nikki would perform the tasks given to her and keep her job for a day, or whether she would quit or be sacked due to her infamous tantrums. The concept of the show was taken from one of the tasks Nikki undertook while in the Big Brother House. During the task, she was assigned as Big Brother's personal assistant and had to carry out various duties, which often resulted in Nikki throwing a tantrum and refusing to comply. The show was often compared to The Simple Life.

The theme music for the programme has been adapted from the 1982 hit single Hey Mickey! by Toni Basil, with the lyrics "Hey Nikki!" used as a replacement.
