No. If you are going to fly your drone for a commercial purpose, i.e. to make money for yourself or someone else or for advertising purposes etc. you must possess a Commercial Drone Pilots License.
If you just flying for fun you do not have be a licensed drone pilot but you are required by the FAA to follow certain rules and fly under the rules of a community based recreational flyer & modeler organization. More information can be found at: www.faa.gov/uas/recreational_fliers/
