Where We Are
Webb County is the largest county in south Texas and is bordered in the west by Mexico. Maverick, Dimmit and La Salle counties share the northern border while McMullen County's southwest corner touches our northeast corner. Duval County is our neighbor to the east and, in the south, we share our border with Jim Hogg and Zapata counties. Laredo is the county seat and is the second largest border town in Texas.
