Cornwall's National Under-20 Championship quarter-final will be held at Camborne RFC on Sunday March 30 with a 2.30 kick off, the CRFU have announced.
The Duchy's opponents in the last eight have yet to be confirmed, but will be the runners-up in the pool containing Berkshire, Gloucestershire, Hertfordshire and Kent.
The outcome of that group is still very much up for grabs, with one round of matches still to be played.
Devon could also still qualify for the last eight if they win their second and final group match at home to Dorset and Wilts.
Cornwall had guaranteed themselves a home quarter-final with an impressive 18-15 victory over old foes Devon at Penryn last month.
The Duchy ensured they finished top of Pool Three by making it back-to-back wins after their 37-35 away triumph over Dorset and Wilts in their opening group game.
The semi-finals of the competition are due to be played on April 13 with the final scheduled for May 4.
