We present a catalogue of 3,305 H$alpha$ emission-line point sources observed with the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) in the vicinity fields of M31 and M33 during September 2011 and January 2016. The catalogue contains 1,487 emission-line stars, 532 emission-line nebulae including 377 likely planetary nebulae (PNe), 83 H~{textsc{ii}} regions candidates and 20 possible supernovae remnants (SNRs) and 1,286 unknown objects. Among them, 24 PN candidates, 19 H~{sc ii} region candidates, 10 SNR candidates and 1 symbiotic star candidate are new discoveries. Radial velocities and fluxes estimated from the H$alpha$ line and those quantities of seven other major emission lines including H$beta$, [O~{textsc{iii}}]~$lambda$4959, [O~{textsc{iii}}]~$lambda$5007, [N~{textsc{ii}}]~$lambda$6548, [N~{textsc{ii}}]~$lambda$6583, [S~{textsc{ii}}]~$lambda$6717 and [S~{textsc{ii}}]~$lambda$6731 lines of all the catalogued sources yielded from the LAMOST spectra are also presented in our catalogue. Our catalogue is an ideal starting point to study the chemistry properties and kinematics of M31 and M33.
