No, Belfast is in Northern Ireland which is part of the UK - you don't need a passport to travel from one part of the country to another.
There is not any direct rail connection between Belfast and France. You will need to travel via London, using ferry service. It will cost you $90 to travel from Belfast to London (ferry and train both), and another $117 to travel to Paris from London via train.
