Tim McInnerny (born 18 September 1956) is an English actor. He is known for his roles in Blackadder as Percy, Duke of Northumberland (series one), Lord Percy (series two) and Captain Darling (series four). He decided not to reprise his role as Percy in series three due to a fear of being typecast, although he did appear in a guest role as half of the Scarlet Pimpernel in the episode "Nob and Nobility" (the other half being played by Nigel Planer). This made him the only person other than Rowan Atkinson and Tony Robinson to appear in all four series of Blackadder, though he did not appear in the one-off special Blackadder's Christmas Carol.

Brother of actress Lizzy McInnerny.

Is an Oxford (Wadham College) graduate.

After playing an essentially similar character called Percy in each of the first two Blackadder series, he declined to reprise the character in "Blackadder the Third" as he felt that the possibilities of playing a bumbling fool had been exhausted. After playing a guest role in one episode of the third series, writers Richard Curtis and Ben Elton persuaded him back into the regular cast for "Blackadder Goes Forth" by offering him a role with a different name (and personality) in the shape of Captain Darling. He is thus the only one of the cast to play differently named regular characters in different series.
