The closest airport is Stansted from which there are direct trains to Cambridge (approx. 30min).

From Heathrow or Gatwick, go via London to get a train from London Kings Cross.
By train :
There are many non-stop services from Kings Cross taking 50min. It is usually preferable to avoid other services since they take longer. Kings Cross is just across the street from the Eurostar arrival in St Pancrass.

There are bus services from Gatwick and Heathrow airport which arrive in the city center (Cambridge Parkers place). Look for National express bus stand which is right by the airport. However it usually takes longer than trains.
