Robert Adley (died 1993) was a politician in the United Kingdom. He served as Conservative Party member of Parliament for Christchurch, England until his death. After his death the seat was won in a by-election by Liberal Democrat Diana Maddock.

Adley was well-known as a railway enthusiast, and as such was often perceived to be something of a romantic Tory. Shortly before his death he strongly attacked the plans then being made by John Major's government for the privatisation of British Rail.
