A CMOS image sensor and a method of fabricating the same are provided. The CMOS image sensor includes: an epitaxial layer of a first conductivity type, formed in a semiconductor substrate of the first conductivity type; a blue photodiode region of a second conductivity type, formed in the epitaxial layer at a first depth; a green photodiode region of the second conductivity type, spaced apart from the blue photodiode region and formed in the epitaxial layer at a second depth larger than the first depth; and a red photodiode region of the second conductivity type, spaced apart from the green photodiode region and formed in the epitaxial layer at a third depth larger than the second depth.
