We present a catalog of sources of very high energy (E>100 GeV) gamma-raysdetected by the Large Area Telescope (LAT) onboard the Fermi Gamma-Ray SpaceTelescope at Galactic latitudes |b|>=10 degrees. We cross-correlate thedirections of individual photons with energies above 100 GeV detected byFermi/LAT with the first year Fermi catalog of sources detected at lowerenergies. We find a significant correlation between the arrival directions ofthe highest energy photons and positions of Fermi sources, with the possibilityof chance coincidences at the level of 1e-45. We present a list of Fermisources contributing to the correlation signal. A similar analysis is performedto cross-correlate the catalog of BL Lac objects with the highest energyphotons detected by Fermi. We produce a catalog of high Galactic latitude Fermisources visible at 100-300 GeV energies. The catalog is divided into two parts.The first part contains a list of 50 higher significance sources among whichthere can be three possible false detections. The second part of the catalogcontains a list of 25 lower significance sources, among which six are possiblyfalse detections. Finally we identify eight additional sources from thecross-correlation analysis with the BL Lac catalog. The reported sources ofE>100 GeV gamma-rays span a broad range of redshifts, up to z~1. Most of thesources are BL Lac type objects. Only 17 out of 83 objects in our list werepreviously reported as VHE gamma-ray sources.
