Spotted dick (also known as "spotted dog" or "railway cake") is a British pudding, traditionally made with suet and dried fruit and often served with custard or a sweetened sauce. Non-traditional variants include recipes that replace suet with other fats (such as butter), or that include eggs to make something similar to a cake.

The dish is first attested in Alexis Soyer's 'The modern Housewife' or 'ménagère', published in 1849, in which he described a recipe for 'Plum Bolster', or Spotted Dick.

The name "spotted dog" first appeared in 1854, in C.M. Smith's "Working-men's Way in the World" where it is described as a "very marly species of plum-pudding". This name, along with "railway cake", is most common in Ireland where it is made more similar to a soda bread loaf with the addition of currants.

The name has long been a source of amusement and double entendres, to the point that the catering staff of Flintshire County Council decided in 2009 to rename it to "Spotted Richard" because of all the jokes they were receiving.

While "spotted" is a clear reference to the dried fruit in the pudding, "dick" and "dog" were dialectal terms widely used for pudding, from the same etymology as "dough"; in late 19th century Huddersfield, a glossary of local terms described 'Dick' as plain pudding. Despite the name change, many Britons still refer to this dessert as Spotted Dick.
