Michael Jolley's U23 development side finished their season with a third successive clean against Category A opposition.
Having beaten Sheffield Wednesday and drawn with Wolves, the Clarets signed off with another shut-out against Middlesbrough on Teesside.
In a game which both sides were cancelling each other out in the middle of the park, Dwight McNeil came close to giving Burnley the lead early on as his powerful drive at goal sailed just over.
The Clarets were pushing for the opening goal and nearly got it as a free-kick from Jamie Thomas was also only inches wide.
Burnley did test the Boro keeper in the second half when Arlen Birch squared the ball to striker Ntumba Massanka, whose effort was tipped just over.
However, despite the best efforts from both sides, neither could find the net as Clarets' keeper Conor Mitchell (above) kept another clean sheet before he reports for a senior Northern Ireland training camp next week.
Jolley's squad has now ended a season in which they have played around 40 games ahead of a planned move into a competitive league next term.
Burnley: Mitchell, Birch, Dunne, Flowers, Trialist, Bayode (Koiki 70) Thomas, Trialist, McNeil, Massanka, Wood (Wilson 65).
