Most, if not all, countries have national anthems but there are few exceptions, as well as unique situations where they may have unofficial or several anthems.

Technically, England, Scotland and Northern Ireland do not have national anthems but unofficial ones that they use or claim is their national song.

• England: God Save the Queen (official national anthem of the UK), Jerusalem, Land of Hope and Glory.
• Scotland: Flower of Scotland (most used), Scotland the Brave, Scots Wha Hae, Auld Lang Syne, as well as a few others.
• Northern Ireland: Londonderry Air, some Irish republicans living in Northern Ireland also favour the Republic of Ireland’s anthem Amhrán na bhFiann.

Wales is the only nation of the UK that has an official national anthem, which is Hen Wlad Fy Nhadau.

The Republic of Cyprus does not have its own unique anthem and shares the Hymn to Liberty with Greece, while Northern Cyprus shares the İstiklâl Marşı with Turkey. This is due to the conflict over the sovereignty of the island between Greece and Turkey, and thus the separate parts identify with either of those two states.

As the other answer indicates, there are also countries with non-lyrical anthems.
