Do all of the outlets in my kitchen need to have ground-fault circuit interrupters?

In kitchens, all outlets that serve countertop surfaces should be equipped with GFCI outlet protection. That would include any outlets on walls, behind wet areas (sinks, etc.) that have features such as countertop breakfast bars on them (open counter surfaces above sinks used to sit at on the opposite side).

That being said, to provide that protection you only need one GFCI outlet as the first outlet of the branch. That would be the outlet that is closest to the serving breaker (not necessarily physically closest but electrically closest), if you can easily identify that outlet. As long as that first outlet is a GFCI, the rest of your outlets on that branch are protected.
