In duplicate bridge pairs tournaments, the Neuberg formula is a method of adjusting match point scores achieved on boards which have been played fewer times than other boards. Originally developed by Gérard Neuberg of France, its objective is to achieve a formula for the final score of every pair to which each hand they have played contributes with equal weight.

Although the objective behind the formula is of questionable soundness, the formula itself follows from well-defined mathematical assumptions, and is almost universally applied in computer-scored bridge tournaments.

A board might have been played fewer times than others because:

The method is:

The formula was developed by Gérard Neuberg, a French mathematician. He died at the end of 2016: there is a brief obituary in the French Bridge Federation magazine (January 2017) .

The formula can also be used for example in a club competition when it is desired to give equal weight to scores achieved over a number of sessions, but there were different numbers of tables at each session.^{[citation needed]}
