My vote goes to Lazenby and Diana Rigg. Admittedly, I think she played the role of the Bond girl better than any other, but I think it was in large part to her chemistry with Lazenby. Their love story came across as natural and genuine.
Others that stood out to me: Pierce and Sophie Marceau (TWINE), Connery and Ursula Andress (Dr. No), Craig and Eva Green (CR).
While it doesn't fit the question (as she isn't a "Bond girl), I also love the rapport between Connery and Lois Maxwell (Moneypenny).
