He followed up his first ATP tour title in Stuttgart with a statement win, beating the French Open winner 7-6 (7-3) 6-3.
He did not lose a service game in a dominant display, though Alcaraz did not lose one in the opening set either, forcing a tie-break before his sloppiness allowed Draper to edge in front.
Despite Alcaraz bringing his usual threat, Draper got a vital break to make it 4-2 in the second set, rallying to see out a third victory against top-10 opposition.
Draper will play fifth seed Tommy Paul in the quarter-finals.
Data Debrief: Alcaraz sees streak snapped
Alcaraz had won eight consecutive matches coming into this meeting thanks to his victory at Roland Garros, but could not find a way past Draper.
The British number one impressed, especially in his serves, winning 76 per cent of his service points during the one hour 39 minute contest.
