We observed the Fermi short GRB200826A (Fermi GBM Team GCN 28284; Mangan 
et al. GCN 28287) with the Giant Metrewave Radio Telescope (uGMRT), 
India, beginning 2020 September 9.53 UT (14.47 days after the burst) at 
a central frequency of 1.25 GHz. We report non-detection of radio 
afterglow from GRB200826A, with no evidence of radio emission above a 
3-sigma upper limit of 48.6 microJy/beam. The final image has a 
resolution of 4.13 arcsec by 1.65 arcsec at a position angle of 83.10 
degrees. We thank the staff of the GMRT that made these observations
