Conflat is a United Kingdom railway term for a short wheelbase flat wagon container wagon.

British Railways used several standard types of wagon. The Conflat A, which could carry one type 'B', or two type 'A', containers, was the most common. It was regularly used to carry AF (frozen food) containers: while the Conflat L, which could carry three smaller containers for bulk powders, was also produced in large numbers.

The Conflat B wagon could carry 2 AFP (frozen food) containers. These were slightly wider than the standard AF containers, and were designed to carry loads on pallets.
