The Grasshopper-class torpedo gunboat was a class of torpedo gunboat built for the Royal Navy in the late 19th century.

The Grasshopper class was designed by Nathaniel Barnaby in 1886 and were essentially repeats of the Rattlesnake of 1886.

They were engined with two sets of Maudslay, Sons & Field triple-expansion steam engines, two locomotive boilers, and twin screws.

This layout produced 1,600 indicated horsepower (1,200 kW) with natural draught and 2,700 indicated horsepower (2,000 kW) with forced draught, giving them a top speed of 19.25 knots (35.65 km/h; 22.15 mph).

[1] They carried 100 tons of coal, giving them a range of about 2,400 nautical miles (4,400 km; 2,800 mi) at 10 knots (19 km/h; 12 mph) and were manned by 66 sailors and officers.
