Narrative: On final to Runway XX around 500 feet AGL; my First Officer and I first started to smell smoke. Initially we thought we were flying through smoke from a fire outside on the ground. There were no signs that the smell was coming from the plane itself. We both scanned the EICAS screens for messages; checked the engine gauges; brake temps; and APU gauges. Nothing was out of the ordinary except the smell. The landing was normal until about 80 or 70 kts when the First Officer called out 'smoke.' As Pilot Flying I was eyes outside and didn't notice it until the First Officer called smoke.At first the smoke looked like heavy fog from the humidity but a little more white. The smoke seemed to be coming from the Captain side vents and from around the rudder pedals. The First Officer side didn't seem to have as much smoke coming out as the Captain side. As we decelerated to make our turn onto Taxiway A6 the smoke began to get thicker. As I taxied the plane clear of the runway I told the First Officer to call the flight attendant. The First Officer reported back to me that there was smoke in the cabin as well.Once I stopped the plane I had the First Officer tell ATC we would be doing an expedited deplaning on the taxiway and to roll the trucks. I then called the flight attendant to see what the status of the cabin was. The flight attendant told me there was a good amount of smoke in the cabin and at that time I told the flight attendant we would do an expedited deplaning using the main cabin door. We ran the QRC for Evacuation/Expedited Deplaning. After getting through the checklist the First Officer jumped out of their seat to open the cockpit door; grab the crash axe; and fire extinguisher. I followed right behind them after checking to make sure all switches and engines were off.By the time I saw the cabin there was some smoke; which appeared to be dissipating as I could see back to the lavatory with little issue. The last passengers off were two able body passengers carrying a man who could not walk down the stairs. The First Officer followed these passengers outside and began to gather everyone in the grass and away from the airplane and away from where the fire trucks might drive. I walked to the back of the plane to make sure there was no one left. It was at this time I saw both over wing exits were used. One passenger had a small cut on her big toe from dropping the over wing exit door on her foot. She asked for a band-aid and that's all she needed. The firemen said there was still smoke coming out from the rudder pedal area but there was no sign of fire. The firemen said there was no sign of a threat anymore. Once all the passengers were gone we got the over wing doors off the wings and put them inside the plane; I dropped the parking brake; closed the main cabin door; and we towed the plane to the terminal ramp.We do not know the cause of the smoke at this time. We do not know what factors caused this event.Depending on what is found in the investigation could lead to improvement of procedures.


Second narrative: On approach to Runway XX at ZZZ; I smelled faint smoke. I verbalized that to the Captain and he concurred and we both thought it was external to the aircraft. There was no notice of any abnormal instrument indications or smoke in the cockpit at that time. Touchdown and rollout were normal. Slowing through about 70 kts; I noticed smoke coming from the Captain side panel. I immediately called out 'SMOKE.' The Captain was preparing to exit on the nearest taxiway. He confirmed that he saw smoke as well and quickly asked for me to contact the flight attendant to see if there was smoke in the cabin. Flight attendant reported that there was some smoke.We assessed the situation and due to the nature and urgency; the Captain told the flight attendant to prepare for an expedited deplaning using the main cabin door. I informed Tower of our condition and they told us they would roll the trucks. The smoke in the cockpit soon increased in amount and thickness. Captain stopped the aircraft and we began to secure the aircraft by completing the QRC Expedited Deplaning Checklist and procedures. I opened the cockpit door and exited the aircraft through the main cabin door. I assisted the last exiting passengers and continued with my First Officer duties.Upon exiting the aircraft; I noticed some passengers on the opposite side of the aircraft; which alerted me to the fact that the passengers evacuated through the over-wing exits. I retrieved those passengers on the other side of aircraft and moved everyone away from aircraft. The fire department and police arrived on the scene at that time.


Synopsis: CRJ-200 flight crew reported smoke in the cockpit during landing that resulted in an evacuation.
