Tipsarevic defeated Alex Bogomolov Jr. of the United States 6-2, 6-1 Saturday to reach his second final in as many weeks, and Cilic ousted 2004 champion and last year's runner-up Mikhail Youzhny 6-3, 6-4.
Bogomolov reached his second semifinal of the season. The Russian-born American also made the final four in Los Angeles in June.
"I made a lot of mistakes, he made few," Bogomolov said.
Cilic won four consecutive games in the first set for a 5-1 lead and broke Youzhny decisively in the ninth game of the second. He closed it out with a drop shot on his first match point.
The fourth-seeded Cilic will be playing in his fourth final this season. He's 5-1 against Tipsarevic, who won in their last meeting in Miami in March.
"I think Janko is playing the tennis of his life these last three months, but I believe I have a good chance this week and I'm going to be really motivated for the final," Cilic said.
Against Bogomolov, Tipsarevic won eight straight games to close out the first set and take a 5-0 lead in the second. Last Sunday, he won his second career title at the Kremlin Cup.
"Even though by the scoreline the match looked pretty easy ... on the court it really didn't feel easy," Tipsarevic said. "I feel I was playing better from the baseline, but the main difference today was that I was serving much better then him.
"I was winning one or two free points off my serve in every game, and he had to fight for every single point because he had no winners from the first shot."
