England to the East, Ireland to the West
No. Britain is an island containing England, Scotland and Wales. Ireland is a separate island. On it are Northern Ireland and what you mistakenly refer to as southern Ireland. That name is neither politically or geographically accurate. It is more commonly referred to as the Republic of Ireland.
It is actually in the midlands of Ireland, close to the centre of the country, so it is not in the north, south, east or west of Ireland. It is in the Republic of Ireland, which is sometimes incorrectly referred to as "Southern Ireland" or the "South of Ireland".
Depending on where you are in Ireland you could say Scotland, the Isle of Man, England or Wales. At different points along the east coast of Ireland, each of these is the next piece of land heading to Ireland's east, meaning Ireland is west of them.
Central Ireland is where it is mostly found, but it can be found in the other areas of the country, in the east, the west, the north and the south.
Ireland is a small country, with an army, but it is a neutral country. It is not a member of any military alliances, like NATO. Ireland's troops have a long and proud history as peacekeepers in countries in the Middle East and Africa.

Dublin is not in Northern Ireland. The term Southern Ireland is an incorrect term often used to refer to what is known as the Republic of Ireland. Dublin is in the Republic of Ireland. Geographically, Dublin is in the east of Ireland, built on the east coast.
Ireland is a country
Dublin is on the east coast of Ireland. In terms of your question it is in what is incorrectly referred to as Southern Ireland. Officially the term is "Ireland" or in the Irish language: "Éire". You will see Éire written on Irish coins and stamps. It is sometimes also referred to as the Republic of Ireland, which is another unofficial term. Dublin is the capital city. See the map below.
Scotland and England (Great Britain) share an island just East of Ireland across the Irish Sea.
Ireland is not a continent it is a country~!
