The Hallmark Sessions is an album by the Canadian jazz guitarist Lenny Breau that was released in 2003.

Elliott Simon, in his All About Jazz review, wrote, "The sound quality, aside from a few minor rough spots, is excellent and the six re-presented stereo versions of the trio pieces sparkle.

"[2] Writing for AllMusic, the critic Scott Yanow gave the album 4.5 out of 5 stars and wrote, "Hallmark Sessions is an extraordinary release... Breau plays beautiful chords (sounding a little like Johnny Smith in spots) and inventive single-note lines.

"[5] In a review for Mint Lounge, Sanjoy Narayan noted that, although the music is "spare," "it shows how effortlessly elegant the young jazz guitarist already was... Breau's style is clean, clear, oozing with talent.

"[6] Russell Carlson of JazzTimes commented: "Breau was a seriously singular guitarist, the kind that can make other, insecure guitarists jealous as all hell... His improvisations were pieces of outside-the-box magic that mixed elements of jazz, country, rock and classical music that, amazingly, didn’t sound contrived.
