The unseeded pair opened tightly, but Vinci produced a break at the vital moment on her way to taking the opening set 6-3.
Youngster Mladenovic had not given up hope, however, as she battled straight back to pull level following a nail-biting end to the second set.
With the two players going into a third and final decider, Vinci perhaps profited from her experience as she broke late before holding out to seal a place in the last four.

Good afternoon everyone and welcome to our live coverage as Kristina Mladenovic takes on Roberta Vinci in the first quarter-final of the US Open at Flushing Meadows.
This quarter-final was always going to be an interesting one given that Maria Sharapova had to pull out and Ana Ivanovic went out early on in the showpiece, but these two women have battled brilliantly to get here. They will be facing each other on the historic Arthur Ashe court in the next 15 minutes or so...
This should be a really interesting spectacle this afternoon, given that both of these players are battling to appear in their first ever Grand Slam semi-final with a victory today.
Mladenovic has perhaps had the harder of the two battles as she had to overcome number 13 seed Ekaterina Makarova in the fourth round. France's underdog won that game with a 7-6(2) 4-6 6-1 triumph over three sets.
As for Vinci, the Italian was given a more easier pass after Eugenie Bouchard had to withdraw through injury during their last-16 clash earlier in the week. The Italian is competing in her third US Open quarter-final today.
This will be a first career fixture between Vinci and Mladenovic, with the latter experiencing an impressive summer. Mladenovic has climbed 41 places from her ranking at the start of the year and will move into the women's top 30 when the new standings are announced next week.
Both players are now out on the court at Ashe and are running through their warmups as we speak.
These ladies will do a good job of managing the heat in New York today. Weather experts are expecting temperatures to peak into the 90s at some point on Tuesday. At 22 years of age, Mladenovic might just shade this on the fitness side of things. The youngster has also had to play a few more sets than Vinci, meaning that she has had the chance to get her eye in and experience the latter stages of these pressurised games at Flushing.
Vinci's game has lots of variety to it, and that could play a part in the outcome as she seeks to outwit the towering Mladenovic. The umpire calls for two minutes - we are almost ready to go!
