We present a multiwavelength study of the Galactic H ii region Sh2-297, located in Canis Major OB1 complex. Optical spectroscopic observations are used to constrain the spectral type of ionizing star HD 53623 as B0V. The classical nature of this H ii region is affirmed by the low values of electron density and emission measure, which are calculated to be 756 cm−3 and 9.15×105 cm−6 pc using the radio continuum observations at 610 and 1280 MHz, and VLA archival data at 1420 MHz. To understand local star formation, we identified the young stellar object (YSO) candidates in a region of area ∼ 7.5′×7.5 ′ centered on Sh2-297 using grism slitless spectroscopy (to identify the Hα emission line stars), and near infrared (NIR) observations. NIR YSO candidates are further classified into various evolutionary stages using color-color (CC) and color-magnitude (CM) diagrams, giving 50 red sources (H−K> 0.6) and 26 Class II-like sources. The mass and age range of the YSOs are estimated to be ∼ 0.1−2 M and 0.5−2 Myr using optical (V/V-I) and NIR (J/J-H) CM diagrams. The mean age of the YSOs is found to be ∼ 1 Myr, which is of the order of dynamical age of 1.07 Myr of the H ii region. Using the estimated range of visual extinction (1.1−25 mag) from literature and NIR data for the region, spectral energy distribution (SED) models have been implemented for selecte
