Human Factors; Procedure
At [Gate] at ZZZ; the First Officer said he saw [Package] near the aircraft; I had just received the cargo load report; so I asked the tug driver over the headset if [Package] was loaded onto the aircraft; he said he would double check and asked someone. He got back to us with that there was no [Package] onboard. I also specifically asked about the presence of dry ice (Dangerous Goods); and the answer I got was that there was not. So neither of those were marked on the cargo load sheet; and neither were onboard according the verbal response I received. I assumed it was coming off our aircraft from the previous flight or destined for another flight. The First Officer during the post flight at [Gate1] at ZZZ1 saw [Package] in our cargo compartment waiting to be unloaded. I do not know if there was any dry ice with it.
EMB-175 Captain reported undocumented Hazmat transported due to a communications breakdown between flight crew and Ramp personnel during preflight.
