Mirfak, Markab, Marchab, 54 Pegasi, HR 8781, BD +14°4926, HD 218045, SAO 108378, FK5 871, HIP 113963.

|} Alpha Pegasi (α Peg / α Pegasi) is the third brightest star in the constellation Pegasus (despite its "alpha" designation) and one of the four stars in the asterism known as the Great Square of Pegasus. It also has the traditional name Markab (or Marchab).

Markab is a relatively average star nearing the end of its stellar evolution on the main sequence. Markab will soon enter the helium burning phase of its development, during which it will likely expand into a red giant. Like the Sun, it will probably end its life quietly as a white dwarf.

The name Markab comes from an Arabic phrase المركب الفرس al-markab al-faras, "the saddle of the horse". An alternative name, Mankib, comes from المنكب الفرس al-mankib al-faras, or "the shoulder of the horse".
