Avicenna is alunarimpact crater that lies on thefar side of theMoon, just beyond the western limb on the northern rim of theLorentz basin. It is named after thePersianpolymathAvicenna. It lies to the north-northwest of the larger craterNernst, and to the southeast ofBragg.

The northern half of Avicenna has been obliterated by subsequent, overlapping impacts. The southern and southeastern rim is worn and eroded, but the outline can still be discerned. There is a small crater lying across the southern rim, although this formation is equally worn. Several small craters lie across the southern extent of Avicenna's floor.

Prior to formal naming by theIAU in 1970,[1] Avicenna was calledCrater 180.[2]
