Compeyson is the main antagonist of Charles Dickens' 1861 novel Great Expectations, a 'George Wickham'-esque man, whose criminal activities harmed two people, who in turn shaped much of protagonist Pip's life.

Clocks were not set, her clothes were never changed, the wedding meal was left in place at her home, Satis House.

She adopted Estella, meaning to bring up the girl to "wreak revenge on all the male sex".

Compeyson's appearance of gentility did not free him of prison time, but the judge and jury looked upon him more favourably, solely due to his social level compared to Magwitch, a boy with no parents, brought up by chance among lower-class people, and nearly always hungry.

Again, Compeyson emphasised the contrast between himself and Magwitch and so the latter was tried again, earning the sentence of transportation for life, in Australia.

Nonetheless, by having jilted Miss Havisham and then dragging Magwitch, as Estella's father, further into a life of crime, he affects the lives of multiple characters in the story, including Pip, and so becomes the antagonist in this novel.
