Mons Agnes is the biggest hill in right part of crater Ina

Mons Agnes is a hill ("mountain") on the Moon, in Lacus Felicitatis, inside crater-like feature Ina, at 18°40′N 5°20′E / 18.66°N 5.34°E. It has maximal width of approximately 650 m[1] (the smallest of all named lunar mountains ar for 2014[2]). Its height is more difficult to determine; from Apollo 15 images it was determined as about 30 m,[1] but newer map, based on LRO photos, gives about 10 m.[3]

Mons Agnes (and all the Ina crater) was discovered on the photos made by Apollo 15 from lunar orbit in 1971.[4] In 1974 NASA published a topophotomap where its name first appeared: it received Greek feminine name Agnes.[1] In 1979 this name (with a term Mons – "mountain") was adopted by International Astronomical Union.[5]

Mons Agnes is one of several dozens of similar hills inside Ina (but one of the largest). Their origin, as for Ina on the whole, remains enigmatic.[6][7]
