This study reports the discovery of 12 new variable stars in the globular cluster M15 using time series observations from 3.6 m DOT and 2 m class HCT. In total, 198 variable stars were detected in the cluster region, including both known and newly discovered variables. Proper motion data from Gaia EDR3 were used to determine the membership of the identified variable stars. The seven of the new variables are found to be probable members of the cluster. Based on variability characteristics and location in the CMD, two of them are likely RR Lyrae type variables. The majority of the known variables are found to be RR Lyrae type variables.
