We have searched for HI 21 cm line emission from shocked atomic gasassociated with southern supernova remnants (SNRs) using data from the SouthernGalactic Plane Survey. Among the 97 sources studied, we have detected 10 SNRswith high-velocity HI emission confined to the SNR. The large velocity and thespatial confinement suggest that the emission is likely from the gasaccelerated by the SN blast wave. We also detected 22 SNRs which show HIemission significantly brighter than the surrounding regions over a wide($>10$\kms) velocity interval. The association with these SNRs is less certain.We present the parameters and maps of the excess emission in these SNRs. Wediscuss in some detail the ten individual SNRs with associated high-velocity HIemission.Comment: 17 pages, 8 figures, accepted for publication in JKAS (Journal of the  Korean Astronomical Society
