The Stonemason's Yard (formally known as Campo S. Vidal and Santa Maria della Carità) is an early oil painting by Giovanni Antonio Canal, better known as Canaletto.

Painted in the mid to late 1720s, it is now in the collection of the National Gallery in London and is considered one of Canaletto's finest works.

The side of the medieval church of Santa Maria della Carità, reconstructed in the 1440s, stands on the opposite bank of the Grand Canal, to the left of the façade of the Scuola Grande della Carità; the tower of the church of San Trovaso is visible rising over the rooftops in the distance.

One woman is using a distaff and drop spindle to spin thread on a balcony to the right; another draws water from a well in the campo beside a wooden shed, from a well-head shaped like the capital of a column.

The view of the opposite bank of the Grand Canal is now blocked by the high arch of the modern wooden Accademia bridge, and the church of the Carità has been much altered.
