We present a catalogue of 3305 Hα emission-line point sources observed with the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) in the vicinity fields of M 31 and M 33 during September 2011 and January 2016. The catalogue contains 1487 emission-line stars, 532 emission-line nebulae including 377 likely planetary nebulae (PNe), 83 H ii region candidates and 20 possible supernova remnants (SNRs) and 1286 unknown objects. Among them, 24 PN candidates, 19 H ii region candidates, 10 SNR candidates and one symbiotic star candidate are new discoveries. Radial velocities and fluxes estimated from the Hα line and those quantities of seven other major emission lines including Hβ,[O iii] λ4959,[O iii] λ5007,[N ii] λ6548,[N ii] λ6583,[S ii] λ6717 and [S ii] λ6731 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 M 31 and M 33.
