Henman, a four-time semi-finalist at the All England Club, has been impressed by the way Murray has negotiated the draw under great pressure and believes the support the British number one will have on Centre Court can give him the edge.
Murray defeated big-serving Pole Jerzy Janowicz in four sets yesterday after Djokovic had needed almost five hours to see off the challenge of Juan Martin del Potro.
Henman told BBC Sport: "Andy has talked about the pressure and expectation that's been put on him this year and, with that in mind, he's performed phenomenally well.
"I felt there was going to be a very positive reaction after he was taken to five sets by Fernando Verdasco and the way he dealt with all the challenges that Janowicz threw at him was sensational."
Murray is aiming to go one better than last year, when he lost in the final to Roger Federer, and has a record of one win from three grand slam finals against Djokovic so far. He is also bidding to become Britain's first Wimbledon men's singles champion since Fred Perry in 1936.
Henman said: "In the context of what has happened in the tournament so far - with Federer and (Rafael) Nadal losing early - this is the final everyone wanted, the final everyone has talked about for the last 10 days.
"When you reflect that Andy has made the final of the last four grand slams he has entered, he's knocking on the door of the top spot and he now has a superb chance against Djokovic.
"It will be interesting to see how Novak responds to playing almost five hours but knowing him - his character, athletic ability, fitness and stamina - I'm sure he'll bounce back.
"However, I said before the tournament that Andy is going to win it and I'm not going to change my tune now.
"The support for him has been amazing and you only needed to be inside Centre Court on Friday to see how the crowd recognised the important moments, when they really needed to get behind him, and he was willing them to get even more involved. It was a great day for tennis and a great day for Murray."
