We present the first deep (72 hours of observations) radio image of theEuclid Deep Field North (EDFN) obtained with the LOw-Frequency ARray (LOFAR)High Band Antenna (HBA) at 144 MHz. The EDFN is the latest addition to theLOFAR Two-Metre Sky Survey (LoTSS) Deep Fields and these observations representthe first data release for this field. The observations produced a 6"resolution image with a central r.m.s. noise of $32\,\mu$Jy\,beam$^{-1}$. Acatalogue of $\sim 23,000$ radio sources above a signal-to-noise ratio (SNR)threshold of 5 is extracted from the inner circular 10 deg$^2$ region. Wediscuss the data analysis and we provide a detailed description of how wederived the catalogue of radio sources and on the issues related todirection-dependent calibration and their effects on the final products.Finally, we derive the radio source counts at 144 MHz in the EDFN usingcatalogues of mock radio sources to derive the completeness correction factors.The source counts in the EDFN are consistent with those obtained from the firstdata release of the other LoTSS Deep Fields (ELAIS-N1, Lockman Hole andBootes), despite the different method adopted to construct the final catalogueand to assess its completeness.
