Lapland (Finnish: Lappi [ˈlɑpːi]; Northern Sami: Sápmi [ˈsaːpmiː]; Swedish: Lappland; Latin: Lapponia) is the largest and northernmost region of Finland. The 21 municipalities in the region cooperate in a Regional Council. Lapland borders the region of North Ostrobothnia in the south. It also borders the Gulf of Bothnia, Norrbotten County in Sweden, Troms and Finnmark County in Norway, and Murmansk Oblast and the Republic of Karelia in Russia. Topography varies from vast mires and forests of the South to fells in the North. The Arctic circle crosses Lapland, so polar phenomena such as the midnight sun and polar night can be seen in Lapland.

Lapland's cold and wintry climate, coupled with its relative abundance of conifer trees such as pines and spruces means that it has become associated with Christmas in some countries, most notably the United Kingdom, and holidays to Lapland are common towards the end of the year. However, Lapland region has developed its infrastructure for year-round tourism and for example 2019 on snow-free period tourism increased more than during the winter season. Rovaniemi Airport is the third busiest airport in Finland. Besides tourism, other important sectors are trade, manufacturing and construction.

The region was associated with Father Christmas or Saint Nicholas when first proposed by Finnish radio host Markus Rautio in 1927.
