We present time series photometry of 57 variable stars in the cluster regionNGC 7380. The association of these variable stars to the cluster NGC 7380 hasbeen established on the basis of two colour diagrams and colour-magnitudediagrams. Seventeen stars are found to be main-sequence variables, which aremainly B type stars and are classified as slowly pulsating B stars, $\beta$ Cepor $\delta$ Scuti stars. Some of them may belong to new class variables asdiscussed by Mowlavi et al. (2013) and Lata et al. (2014). Present sample alsocontains 14 pre-main-sequence stars, whose ages and masses are found to bemostly $\lesssim$ 5 Myr and range 0.60 $\lesssim M/M_{\odot} \lesssim$ 2.30 andhence should be T-Tauri stars. About half of the weak line T-Tauri stars arefound to be fast rotators with a period of $\lesssim$ 2 days as compared to theclassical T-Tauri stars. Some of the variables belong to the field starpopulation.
