  LHC data show a diphoton excess at 750 GeV and a less significant diboson
excess around 1.9 TeV. We propose trinification as a common source of both
anomalies. The 1.9 TeV excess can be produced by the lightest extra vector: a
$W_R^\pm$ with a gauge coupling $g_R\approx 0.44$ that does not decay into
leptons. Furthermore, trinification predicts extra scalars. One of them can
reproduce the $\gamma\gamma$ excess while satisfying constraints from all other
channels, given the specific set of extra fermions predicted by trinification.
