We identify likely near- infrared counterparts to submillimetre sources in the South Galactic Pole (SGP) field using the VISTA VIKING survey. We search for the most probable counterparts within 15 arcsec of each Herschel source using a probability measure based on the ratio between the likelihood the true counterpart is found close to the submillimetre source and the likelihood that an unrelated object is found in the same location. For 110374 (57.0 per cent) sources, we find galaxies on the near-infrared images where the probability that the galaxy is associated to the source is greater than 0.8. We estimate the false identification rate to be 4.8 per cent, with a probability that the source has an associated counterpart on the VIKING images of 0.835 +/- 0.009. We investigate the effects of gravitational lensing and present 41 (0.14 deg^-2^) candidate lensed systems with observed flux densities >100 mJy at 500 {mu}m. We include in the data release a probability that each source is gravitationally lensed and discover an additional 5923 sources below 100 mJy that have a probability greater than 0.94 of being gravitationally lensed. We estimate that ~400-1000 sources have multiple true identifications in VIKING based on the similarity of redshift estimates for multiple counterparts close to a Herschel source. The data described in this paper can be found at the H-ATLAS website.2022MNRAS.510.2261Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/510/2261CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/236/30 : Herschel-ATLAS (H-ATLAS) DR2 (Maddox+, 2018)II/329 : VIKING catalogue data release 1 (Edge+, 2013)II/343 : VIKING catalogue data release 2 (Edge+, 2016)II/294 : The SDSS Photometric Catalog, Release 7II/347 : KiDS-ESO-DR3 multi-band source catalog (de Jong+, 2017)VII/233 : 2MASS All-Sky Extended Source Catalog (XSC)J/ApJS/199/26 : The 2MASS Redshift Survey (2MRS) (Huchra+, 2012)J/AJ/116/1 : Southern Sky Redshift Survey (Da Costa+, 1998)VII/250 : The 2dF Galaxy Redshift Survey (2dFGRS)VII/259 : 6dF galaxy survey final redshift release (Jones+, 2009)www.h-atlas.org : H-ATLAS data web pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/510/2261https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/510/2261http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/510/2261https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/510/2261https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/510/2261http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/510/2261GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/510/2261/hatlasgp (H-ATLAS DR3 catalogue for the SGP field keeping the best VIKING ID counterparts)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/510/2261/hatlasgp?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/510/2261/hatlasgp?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/510/2261/hatlasgp?GETtext/xml+votable180.050000true0.00016111-32.557861940.005555555555555556Cone search capability for table J/MNRAS/510/2261/hsgpall (H-ATLAS DR3 catalogue for the SGP field with all included VIKING couterparts IDs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/510/2261/hsgpall?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/510/2261/hsgpall?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/510/2261/hsgpall?GETtext/xml+votable180.050000true0.00016111-32.557861940.0055555555555555564/1027-1029 1032 2230 2233-2234 2911 2931-2932 5/4101-4103 4105-4107 4120-4122 4132-4134 4136-4138 4160 8890 8893-8895 8909-8911 8914 8929-8931 8940 8942 8944 11637-11639 11642-11643 11717 11719 11732-11734 11736-11738 6/16399 16403 16419 16492 16496 16500-16501 16540 16556-16557 16560 16576 16644-16646 16648-16650 16652 16672 16896 16898 35519 35549-35551 35565-35567 35569-35571 35613-35615 35629-35631 35633-35635 35662 35698 35704-35706 35713-35715 35764-35766 35780-35782 35784-35786 46463 46543 46547 46563 46565-46567 46873-46875 46887 46893 46895 46940 46956-46958 46960-46962 46993 46996-46997 46999 47040-470423.972892068905477e-22 4.653515163505597e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/510/2261?format=asciiOpticalInfraredMillimeterdefaultJ/MNRAS/510/2261/hatlasgpH-ATLAS DR3 catalogue for the SGP field keeping the best VIKING ID counterpartsrecnoRecord number assigned by the VizieR team.
