Trouble with Lichen (published 1960) is a science fiction novel by John Wyndham. It is intended as a social satire; opinion varies as to its quality. It is not generally regarded as one of Wyndham's best novels, but some consider it an interesting and entertaining piece nevertheless.

The plot concerns a young woman biochemist who discovers that a chemical extracted from an unusual strain of lichen (hence the title) can be used to retard the ageing process, enabling people to live to around 200-300 years. Wyndham speculates how society would deal with this prospect.
