Eibar lies at an altitude of 121m above sea level, in the west of the province of Gipuzkoa, very close to Biscay.

[4] Apart from the urban area, the municipality consists of five rural neighbourhoods: Otaola-Kinarraga, Aginaga, Arrate, Mandiola and Gorosta.

Eibar, like the rest of settlements in the valley, had an industry based on finery forges and arms manufacturing.

In 1766, Eibar was engaged in a social revolt known as the Machinada, and years later, in 1794, it was attacked by the French, who destroyed the town.

[6] In the 19th century, industrialisation transformed the systems of production in the city and spawned a powerful social movement.

[6] The AP-8 motorway connecting Bilbao and the French border crosses through Eibar, as does the N-634 road running parallel to it.

[22] Regular and frequent bus services under Lurraldebus [eu] connect Eibar to neighbouring towns, San Sebastián, Vitoria-Gasteiz and Bilbao Airport.

The women's section of SD Eibar was granted promotion to the Primera División in the 2019–20 season.

The Astelena fronton, nicknamed the Cathedral of Basque Hand-pelota, is a regular venue of the hand-pelota professional circuit competitions the Bare-handed Pelota First League, the Bare-handed Pelota First League Doubles and the Cuatro y Medio Euskadi Championship.

Since 2009, the city has hosted an annual stage finish in the Tour of the Basque Country, usually after the riders have climbed the Alto de Arrate.
