Do France passport holders need a visa to visit IE?

No visa is required. French citizens are EU nationals with full freedom of movement and can enter Ireland for tourism or any short visit with just a valid passport or national ID card. Ireland is not in the Schengen Area and is not joining ETIAS, so no travel authorisation is needed. France (FR) is a European Union member state, and Ireland (IE) is also an EU member state, so French citizens travel to Ireland under EU free-movement rights. No visa, no pre-clearance, and no ETIAS travel authorisation is required for a tourist or short visit. A French national simply presents a valid passport or a valid national identity card at the border. Although Ireland is in the EU, it is NOT part of the Schengen Area, so the Schengen 90/180-day short-stay rule does not apply to Ireland; instead Ireland operates the Common Travel Area with the UK. Ireland has also confirmed it will not operate the EU's Entry/Exit System (EES) or ETIAS, both because it is outside Schengen and to preserve the Common Travel Area. As an EU citizen, a French visitor can stay for up to 3 months freely; staying beyond 3 months is permitted only if exercising an EU Treaty right (work, self-employment, study, or self-sufficiency with sickness insurance), but no residence permit or registration is required even then. There is no fee of any kind for entry.
