Ukraine is a country in Eastern Europe. It borders Russia to the north-east, Belarus to the north, Poland, Slovakia and Hungary to the west, Romania and Moldova to the south-west, and the Black Sea and Sea of Azov to the south. The historic city of Kiev (Kyiv) is the country's capital.

From at least the ninth century, the territory of present-day Ukraine was a centre of medieval East Slavic civilization forming the state of Kievan Rus, and for the following several centuries the territory was divided between a number of regional powers. After a brief period of independence (1917–1921) following the Russian Revolution of 1917, Ukraine became one of the founding Soviet Republics in 1922. The Ukrainian Soviet Socialist Republic's territory was enlarged westward after the Second World War, and again in 1954 with the Crimea transfer. In 1945, Ukrainian SSR became one of the co-founder members of the United Nations. It became independent again after the Soviet Union's collapse in 1991.

At 603,700 km² (233,074 mi²) and with a coastline of 2,782 km, Ukraine is the world's 44th-largest country (after the Central African Republic, before Madagascar). It is the second largest country in Europe (after European part of Russia, before metropolitan France).

There is ongoing debate on where the geographical centre of Europe is, for instance, some claim the center is near the small town of Rakhiv, in western Ukraine;.

The Ukrainian landscape consists mostly of fertile plains, or steppes, and plateaus, crossed by rivers such as the Dnieper, Seversky Donets, Dniester and the Southern Buh as they flow south into the Black Sea and the smaller Sea of Azov. To the southwest the delta of the Danube forms the border with Romania. The country's only mountains are the Carpathian Mountains in the west, of which the highest is the Hora Hoverla at 2,061 metres (6,762 ft), and those in the Crimean peninsula, in the extreme south along the coast.

Ukraine has a mostly temperate continental climate, though a more mediterranean climate is found on the southern Crimean coast. Precipitation is disproportionately distributed; it is highest in the west and north and lesser in the east and southeast. Winters vary from cool along the Black Sea to cold farther inland. Summers are warm across the greater part of the country, but generally hot in the south.

The culture of Ukraine has been formed by influences of its eastern and western neighbors, and the architecture, music and dance of Ukraine all reflect this.

Communist rule had quite a strong effect on the art and writing of Ukraine. During the late 1920s and early 1930s, the Soviets began enforcing the socialist realism art style in Ukraine; this style dictated that all artists and writers glorify the Soviet Regime with their talents. After the Soviet Union collapsed, Ukrainian artists and writers again became free to express themselves as they wanted.

The tradition of the Easter egg had its beginnings in Ukraine: these eggs were drawn on with wax to create pattern; dye was then added to give the eggs their delightful colors - the dye not affecting the wax-coated parts of the egg. Once the whole egg was dyed, the wax was removed leaving only the colorful pattern. The tradition is thousands of years old, and predates the arrival of Christianity in the country.

Ukrainians also have food culture which dates back to the old time. The Ukrainian diet includes chicken, pork, beef, fish and mushrooms. Ukrainians eat a lot of potatoes, grains, fresh and sour vegetables, different kinds of bread. Popular traditional dishes include varenyky (boiled dumplings with mushrooms, potatoes, sauerkraut, cottage cheese or cherries), borsch (soup made of beets, cabbage and mushrooms or meat) and holubtsy (stuffed cabbage rolls filled with rice, carrots and meat). Ukrainian specialties also include Chicken Kiev and Kiev Cake. Ukrainians drink stewed fruit, juices, milk, sour milk (They make cottage cheese from this), mineral water, tea and coffee, beer, wine and vodka.

The Ukrainian word Ukrayina stems from the Old Slavic root kraj-, a homonym meaning "edge" or "borderland" as well as "land", "region", "country" (see main article). In particular, in Ukrainian krayina means simply "country".

In English, the country is sometimes referred to with the definite article, the Ukraine, as in the Netherlands, the Gambia, the Sudan or the Congo. However, usage without the article is now more frequent, and has become established in journalism and diplomacy (e.g. The Economist, Times) since the country's independence.
