We present time series photometry of 57 variable stars in the cluster region NGC 7380 .
The association of these variable stars to the cluster NGC 7380 has been established on the basis of two colour diagrams and colour-magnitude diagrams .
Seventeen stars are found to be main-sequence variables , which are mainly B type stars and are classified as slowly pulsating B stars , \beta Cep or \delta Scuti stars .
Some of them may belong to new class variables as discussed by Mowlavi et al .
( 2013 ) and Lata et al .
( 2014 ) .
Present sample also contains 14 pre-main-sequence stars , whose ages and masses are found to be mostly \lesssim 5 Myr and range 0.60 \lesssim M / M _ { \odot } \lesssim 2.30 and hence should be T-Tauri stars .
About half of the weak line T-Tauri stars are found to be fast rotators with a period of \lesssim 2 days as compared to the classical T-Tauri stars .
Some of the variables belong to the field star population .
