HMS Belette (or Bellette) was an 18-gun Cruizer-class brig-sloop, built by Edward Larking and William Spong at Kings Lynn and launched in 1814.

At Halifax Belette enforced the obligations under the Treaty of Ghent with respect to revenue and fisheries.

[2] In carrying out these duties she took into custody numerous vessels of varying types that she suspected of violating the Treaty or the revenue laws.

The vessel was purportedly only carrying flour and stores, but a close search found the concealed goods.

In the summer of 1820 Bellette patrolled Passamaquoddy Bay on the border with the United States to stop the illegal plaster trade.
