According to the old folk, the Bunga Pekan flower grows wild at the banks of Pahang River. The river at the Pekan town (near Mengkasar village) is also called Pekan River, however there is no source for the claim that Pekan got its name from this river. Other sources say the name "Pekan" came from the word "Pekan Pahang" (town of Pahang).For easier pronunciation, the locals simply called it "Pekan" and the name is still used.
