The National 199er Pairs national bridge championship was held until 2013 at the summer American Contract Bridge League (ACBL) North American Bridge Championship (NABC).
The National 199er Pairs was a one-day, two-session matchpoint pairs event. The event typically started on the second Thursday of the NABC and was restricted to players with fewer than 200 masterpoints.
