SMS Niobe was a Diamond-class 28-gun sixth-rate sailing frigate built for the Royal Navy in the 1840s. She was never commissioned into the Royal Navy, which was converting to steam power, and was sold to Prussia in 1862. She was named after Niobe, a figure from Greek mythology. She served with the Prussian Navy, the Norddeutsche Bundesmarine and the Kaiserliche Marine as a training ship until stricken and hulked in 1890. Niobe was eventually broken up in 1919.
