World number eight Ruud triumphed 6-1, 4-6, 7-6 (7/2), 6-3 and will meet 2014 US Open champion Marin Cilic for a place in Sunday's final.
Rune, ranked 40, had knocked out fourth seed and 2021 runner-up Stefanos Tsitsipas in the fourth round.
The 19-year-old was bidding to become the first Danish man to reach the last-four in Paris and first at any Slam since Jan Leschly at the 1967 US Championships.
However, Ruud overpowered the youngster, firing 13 aces and 55 winners while Rune had to fight off 12 of 17 break points carved out by the Norwegian.
Earlier Cilic launched 33 aces and 88 winners past seventh-seeded Andrey Rublev to reach his first French Open semi-final with a 5-7, 6-3, 6-4, 3-6, 7-6 (10/2) win.
