In seismic response investigation, shear wave velocity, Vs shows a vigorous role as an input factor. Enormous methodologies have been developed and tested to directly determine this key factor. Direct measurement of V<sub>s </sub>is time-consuming as well as highly expensive. As a result, researchers from different regions have tried to reduce the difficulties associated with the measurement and developed empirical relationships between V<SUB>S</SUB> and other geotechnical characteristics of the soil, such as SPT calculation, depth, vertical effective pressure, etc. In this paper, the empirical correlation between shear wave velocity and standard penetration number (SPT-N) has been investigated for several soil categories: all soils, sand, silt and clay-type soils. Study area selected for this analysis are Bagha, Bagmara, Charghat, Durgapur, Godagari, Paba, Puthia, Tanore and Rajshahi City Corporation (RCC) area consisting of 36 borehole dataset. Combining all the data, an approach is made to correlate the Vs with the SPT-N. The square value of the coefficient (R<sup>2</sup>) of correlation shows good agreement with the subsoil. Regression analysis is used to propose an empirical relation for this zone which would be helpful for foundation engineers to have the idea on earthquake response analysis of subsoil.
