The Principlists (, ), also interchangeably known as the Iranian Conservatives and formerly referred to as the Right or Right-wing, are one of two main political camps in post-revolutionary Iran; the Reformists are the other camp. The term hardliners that some Western sources use in the Iranian political context usually refers to the faction. The faction rejects the status quo internationally, but favors domestic preservation.
According to a poll conducted by the Iranian Students Polling Agency (ISPA) in April 2017, 15% of Iranians identify as leaning Principlist. In comparison, 28% identify as leaning Reformist.
In April 2021, a joint public opinion survey conducted by the Chicago Council on Global Affairs and IranPoll found out that 19% of Iranians identified as Principlist while 7% were leaning Principlist, and if Reformists (21%) and leaning Reformist (10%) were still higher, they also noted that "the support base for the reformists has shrunk by about 8 percentage points since 2017, while the support base for the conservatives has grown by 4 percentage points."
