Narrative:

Upon arriving at the gate in ZZZ; we (cockpit crew) were given a hazmat cargo report with the normal paper work operations agents give the cockpit upon arrival. I initially thought we (crew) were going to be taking hazmat on our next flight; but after looking at the 'origin/destination' section of the report; I realized it was for the flight that was just completed. I went up the jetway and inquired about the hazmat report we (cockpit crew) were given and informed the operations agent that we (cockpit crew) were unaware of any hazmat onboard. The operations agent called a supervisor who came to the gate and I informed them (supervisor and operations agent) that we (cockpit crew) were unaware of any hazmat onboard; and were not given any verbal notification or a notac to sign before we departed from ZZZ1. I contacted the chief pilot on call to apprise them of the situation and to see if there were any hoops we (cockpit crew) had to jump through or boxes that need to be checked before we (crew) continued on our next flight.
