Machico is a municipality, parish and city in the southeast part of the island of Madeira, in the Autonomous Region of Madeira. The easternmost municipality on the island, it is also the third-most populous area with a population of 21,828 in 2011. The town, proper, had a population of 10,894 in 2001.

The economy is focused on agriculture, tourism, and fishing, although a small number of businesses and commercial establishments have concentrated in the centre of town. The main harbour is a mixture of personal and public uses, that includes a lighted promenade, scenic landscapes of the town, as well as a small harbour that is used as a fishing port and public harbour (usually filled with yachts).

Machico is located 17 km northeast of Funchal, northwest of the uninhabitable Savage Islands, 20 km southeast of Santana and west-southwest of Porto Santo in the extreme eastern portion of the island of Madeira. It is linked by road from Funchal (the regional capital), to the Santana and the villages of Ribeira Seca and Caniçal. To the existence of mountains on the western coast, it is sandwiched along the coast from the rest of the islands' settlements, while forests lie towards the interior and grasslands cover the north-eastern corner of the municipality.

Geomorphologically, the municipality is dominated by steeped and inclined topography, except in the Machico valley (where slopes are gentle), formed by two mountain ranges: in the east Pico do Facho and to the west the Queimada plateau. Examples of these differences include the area south of Porto da Cruz (in the watershed of Ribeira do Juncal) and in Caniçal (in the Ribeira da Palmeira watershed).

Due to its location and morphological characteristics, the climate of Madeira is complex, whose difference from place to place is accentuated, even in areas relatively close. Machico temperatures are relatively moderate throughout the year, with variation relatively low (only accentuated between elevations).
