Stéphane Tétreault (born 10 April 1993) is a Canadian cellist.

He first made international headlines as the recipient of Bernard Greenhouse's cello,[1][2] the 1707 "Countess of Stainlein Ex-Paganini" Stradivarius, loaned to him by Mrs. Jacqueline Desmarais and following her death, by her daughter Mrs. Sophie Desmarais.

Stéphane Tétreault has been praised by the world's leading music critics: "Tétreault’s disc charmed me from the off; this is just pure, lyrical, unadulterated playing of the highest order, with a maturity that belies his 22 years...

(Charlotte Gardner, Gramophone),[3] "His vibrato and tone are varied, his bowing techniques immaculate and his awareness of harmony and consequent shading omnipresent."

(Joanne Talbot, The Strad),[4] "The solo playing is astonishingly mature not merely in its technical attributes but also in its warmth, brilliance and subtlety of colour and inflection."
