The Halfpenny Rose Red, first issued on 1 October 1870, was the first halfpenny postage stamp issued in the United Kingdom.

The halfpenny stamp was introduced following a reduction in the postal rate for newspapers and postcards.

It was designed to be approximately half the size of the corresponding one penny stamp and is notable for being the smallest UK postage stamp ever issued at 17.5 mm × 14 mm (0.69 in × 0.55 in).

They were line engraved and featured a bust of Queen Victoria in profile with '½d' on either side.

A plate number was engraved in the design, in the left and right side lace work.
