Trouble with Lichen (published 1960) is a science fiction novel by British writer John Wyndham.

The plot concerns a young female biochemist who discovers that a chemical extracted from an unusual strain of lichen can be used to slow down the ageing process, enabling people to live to around 200–300 years. Wyndham speculates how society would deal with this prospect.
