Malta, officially the Republic of Malta, is a small and densely populated island nation comprising an archipelago of seven islands in the Mediterranean Sea. A country of Southern Europe, Malta lies south of Sicily, east of Tunisia, and north of Libya. The country's official languages are Maltese and English. Roman Catholicism is the most practised religion. The islands constituting the Maltese nation have been ruled by various powers and fought over for centuries. Malta has been a member state of the European Union (EU) since 2004 and it is currently the smallest EU country both in population and in area.

Malta is an archipelago in the central Mediterranean Sea (in its eastern basin), some 93 km south of the Italian island of Sicily across the Malta Channel; east of Tunisia and north of Libya in Africa. Only the three largest islands Malta Island (Malta), Gozo (Ghawdex), and Comino (Kemmuna) are inhabited. The smaller islands, such as Filfla, Cominotto and the Islands of St. Paul are uninhabited. Numerous bays along the indented coastline of the islands provide good harbours. The landscape is characterised by low hills with terraced fields. The highest point is at Ta' Dmejrek on Malta Island at 253 metres (830 ft) near Dingli. Although there are some small rivers at times of high rainfall, there are no permanent rivers or lakes on Malta. However some watercourses are found randomly around the island that have fresh water running all year round. Such places are Bahrija, Imtahleb and San Martin. Running water in Gozo is found at Lunzjata Valley.

The climate is Mediterranean (Köppen climate classification Csa), with mild, rainy winters and hot, dry summers. There is no real thermal dormant season for plants, although plant growth can be checked briefly by abnormal cold in winter (patches of ground frost may occur in inland locales), and summer heat and aridity may cause vegetation to wilt. Effectively there are only two seasons, which makes the islands attractive for tourists especially during the drier months. However, strong winds can make Malta feel cold during the spring months.

Water supply poses a problem on Malta, as the summer is both rainless and also the time of greatest water use, and the winter rainfall often falls as heavy showers and runs off to the sea rather than soaking into the ground. Malta depends on underground reserves of fresh water, drawn through a system of water tunnels called the Ta' Kandja galleries, which average about 97 m. below surface and extend like the spokes of a wheel. In the galleries in Malta's porous limestone, fresh water lies in a lens upon brine. More than half the potable water of Malta is produced by desalination, which creates further issues of fossil fuel use and pollution.
In January 2007, International Living chose Malta as the country with the best climate in the world.
