  In this paper, we study inflation with {\alpha}-attractor potential in the RS
braneworlds where high energy corrections to the Friedmann equation facilitate
slow roll. In this scenario, we numerically investigate the inflationary
parameters and show that the high energy brane corrections have significant
effect on the parameter {\alpha}, namely, the lower values of the parameter are
preferred by observation in this limit. We find that the sub-Planckian values
of the field displacement can be achieved by suitably constraining the brane
tension.
