Leckwith (Welsh: Lecwydd) is an area in the west of Cardiff that includes parts of the communities of Canton and Grangetown.

The area shares its name with the village of Leckwith which is situated on the other side of the river Ely in the Vale of Glamorgan.

Historically, the parish of Leckwith included lands on both sides of the river; the low-lying marshy lands on the Cardiff side were known as the Leckwith Moors.

But as the Cardiff Leckwith has no official status the area has no formal boundaries and the name is sometimes used for locations outside the historic parish.

The old stone triple-arched Leckwith Bridge crosses the river Ely to the west.
