Abstract: Based on archival images from the Hubble Space Telescope (HST), candidates for massive stars in the galaxy NGC 628 were selected. Using constructed color-magnitude diagrams, stellar clusters containing bright blue stars were identified and compared with the locations of H. regions in images obtained from various telescopes. A total of 22 stars were selected. Spectroscopy was performed for 17 stars based on archival data of this galaxy using images from the MUSE (Multi Unit Spectroscopic Explorer) spectrograph on the VLT telescope. Among these, 11 objects exhibited spectra without stellar features, 2 objects were classified as WR stars, and 2 as B[e]-supergiants. The results of spectroscopy for two bright massive stars in the galaxy NGC 628, which exhibited LBV characteristics, are presented.
