Juno-class corvettes were a group of two ships built for the Royal Navy during the 1860s in London to a design by Sir Edward Reed.

Juno was built by Deptford Dockyard and laid down in 1866, launched on 28 November 1867 and completed in May 1868.

It had a displacement of 2,240 tons, its crew numbered 200, top speed it achieved was 11.13 knots, and it was armed with two 7-inch MLR and four 64-pounder cannons.

Note Thalia was the last ship to be built at Woolwich Dockyard, and received the engine intended originally for the cancelled (1864) wooden frigate Ister.

The ships were made alongside 35 others in the 1867-1868 programme written in the Parliamentary Debates.
