T\bar{T}-deformations of conformal field theories have been widely studied in the past years, in particular in light of their holographic relation to AdS_3 at finite cutoff. I will introduce a new way of thinking about such deformations to first order as coming from 4D Chern-Simons theories. Namely, I will show that starting with a 4D Chern-Simons theory coupled with 2D chiral and anti-chiral CFTs, one can recover a 2D (infinitesimally) T\bar{T}-deformed theory by integrating out the Chern-Simons gauge field. I will present a couple of examples leading to deformed theories on curved spaces with different geometries.
