We present a complete census of all Herschel-detected sources within the six massive lensing clusters of the HST Frontier Fields (HFF). We provide a robust legacy catalogue of 263 sources with Herschel fluxes, primarily based on imaging from the Herschel Lensing Survey and PEP/HerMES Key Programmes. We optimally combine Herschel, Spitzer and WISE infrared (IR) photometry with data from HST, VLA and ground-based observatories, identifying counterparts to gain source redshifts. For each Herschel-detected source we also present magnification factor (mu), intrinsic IR luminosity and characteristic dust temperature, providing a comprehensive view of dust-obscured star formation within the HFF. We demonstrate the utility of our catalogues through an exploratory overview of the magnified population, including more than 20 background sub-LIRGs unreachable by Herschel without the assistance gravitational lensing.

These observations are associated with programmes #11689, 13389, 13495, 13496, 13498, 13504. This publication also uses data products from the Wide-field Infrared Survey Explorer ( WISE), which is a joint project of UCLA and JPL, Caltech, funded by NASA. This research made use of the NASA/IPAC Infrared Science Archive, which is operated by JPL, Caltech, under contract with NASA.; We made use of a private version of the Rainbow Cosmological Surveys Database, operated by the Universidad Complutense de Madrid (UCM), and PGP-G acknowledges support from Spanish Government MINECO grant AYA2012-31277.; This work also utilizes gravitational lensing models produced by PIs Ebeling (CATS) and Merten & Zitrin, funded as part of the HST Frontier Fields program conducted by STScI. STScI is operated by the Association of Universities for Research in Astronomy, Inc. under NASA contract NAS 5-26555. The lens models were obtained from the Mikulski Archive for Space Telescopes (MAST).
