Ribeira da Janela is a civil parish (Portuguese: freguesia) in the municipality of Porto Moniz in the Portuguese islands of Madeira.

[3] It is located northeast coast of the municipality of Porto Moniz, connected by the main roadway that circles the island to the principal communities in Funchal and Calheta.

Mountainous, the parish is cut by several river valleys extending into the Atlantic Ocean from the interior plateau of Paul da Serra, where it borders the municipalities of Ponta do Sol and Calheta.

The ravine, Ribeira da Janela, meanders through the parish from Paul da Serra (springing from the plateau at around 1,420 metres altitude) and flows at various intervals along the water course.

Forests dominate the northern and the western parts of the valley and while brush characterises the remaining areas.
