The A-class torpedo boats were a class of German single-funnelled torpedo boat/light destroyer designed by the Reichsmarineamt for operations off the coast of occupied Flanders in the First World War.

They were classed officially as "coastal torpedo boats" (German: Küstentorpedoboote) to differentiate from larger, ocean-going torpedo boats.

All had a raised forecastle, shallow draught, and carried one (for most) or two (for A1-A25) 17.7 in (45 cm) torpedo tubes amidships.

All were designed and built by F. Schichau Werke, at their Elbing yard.

These twelve vessels were ordered in 1916, and were designed and built by F. Schichau at Elbing.
