Procedure; Human Factors
We were configuring the aircraft to final flaps and doing the checklist when we were given the instructions to switch to the Tower; by Miami Approach. We acknowledged the transmission. After completing the checklist I then resumed my pilot not flying duties; but forgot to switch over to the Tower and we landed on Runway 8R without landing clearance. We had not even realized we had done so until we stated that we were clear of the runway; and that's when Miami Approach stated that we were still on their frequency. We then immediately switched over to the Tower and told them that we were clear of the runway and what had happened and they said no problem and to taxi to our parking spot on the ramp. The Captain and I were very exhausted and we both were positive we were given landing clearance; but that was obviously not the case.
The incident occurred at the end of a three leg 11 hour night turn. Arriving in Miami we were given vectors to follow traffic to [Runway] 8R. Once calling traffic in sight we were cleared for visual behind traffic. We landed safely; exited runway and [called] for taxi clearance. We were advised we were back on Approach. We then realized we had not been handed off to Tower and cleared to land. We called Ground/Tower and were cleared to ramp as normal. Fatigue was a major contributor to the incident.
After landing in MIA; a fatigued flight crew realized that they were on Approach Control frequency and had not received landing clearance.
