Portuguese pavement (calçada portuguesa, European Portuguese: [kɐɫˈsaðɐ puɾtuˈɣezɐ], Brazilian Portuguese: [kawˈsadɐ poʁtuˈɡezɐ]) is a traditional-style pavement used for many pedestrian areas in Portugal. It consists of small flat pieces of stones arranged in a pattern or image, like a mosaic. It can also be found in Olivença (a disputed territory administered by Spain) and throughout old Portuguese colonies, such as Brazil and Macau. Portuguese workers are also hired for their skill in creating these pavements in places such as Gibraltar. Being usually used in sidewalks, it is in squares and atriums that this art finds its deepest expression.
The Romans used to pave the vias connecting the empire using materials to be found in the surroundings. Some of the techniques introduced then are still applied on the calçada, most noticeably the use of a foundation and a surfacing.

Very little new paving is done and the entire profession is at risk. The long hours and low wages typical of calceteiros have reduced apprenticeships and thus new pavers. Furthermore, as the pavement is less safe (provides less traction when wet; loose stones can become tripping hazards), costs more (especially with the difficulty of obtaining appropriate stones), and wears quicker than concrete or asphalt, there is also dropping interest in investment and construction in it. Although there were once hundreds of calceteiros, most modern work is on conservation or major architectural projects.
While São Paulo is currently replacing the Portuguese pavement sidewalks of Paulista Avenue with a cheaper type of pavement, other Brazilians cities such as Rio de Janeiro still have nearly ubiquitous Portuguese pavement, particularly in more affluent areas.
