The 23-year-old Belarusian, playing in her first Grand Slam quarterfinal, played aggressively throughout to keep 21st seed Jabeur on the back foot.
She will take on Czech Karolina Pliskova in the last four.
Jabeur, who had made history by becoming the first Arab woman to reach the Wimbledon quarterfinals, boasts one of the most versatile styles in the women’s game.
But Sabalenka played the match on her own terms to nullify Jabeur’s weapons, gaining the first break of serve in the match in the 10th game to move into a one-set lead.
Sabalenka struck first in the second set and although Jabeur hung on gamely she was unable to resist the power coming from the other side of the net.
Jabeur had a breakpoint when Sabalenka served for the match at 5-3 but could not convert it and the Belarusian finished it off with her 27th winner of the match, a backhand down the line.
