We provide a preliminary data release from the LOFAR Two-metre Sky Survey (LoTSS). This release covers 381 square degrees (right ascension 10:45:00 to 15:30:00 and declination 45:00:00 to 57:00:00) and contains 44,500 sources which were detected with signal in excess of seven times the local noise in our 25" resolution images. The noise varies across the surveyed region but is typically below 0.5mJy/beam and we estimate the catalogue to be 90% complete for sources with flux densities in excess of 3.9mJy/beam.
