Provided is a multi-well CMOS image sensor and a method of fabricating the same. The multi-well CMOS image sensor may include a plurality of photodiodes vertically formed in a region of a substrate, an n+ wall that vertically connects an outer circumference of the photodiodes, and a floating diffusion region that is connected to the photodiodes on a side of the n+ wall to receive charges from the photodiodes, wherein a p-type region is formed between the floating diffusion region and the n+ wall, and the plurality of photodiodes have a multi-potential well structure.
