I personally don't know any gambit, I just try to play the opining following the basic principles. I saved this list from a comment in Reddit time ago:
Unavoidable 2nd move gambits:
King's Gambit against 1.e4 e5.
Smith-Morra against the Sicilian.
Staunton Gambit against the Dutch.
Blackmar-Diemer Gambit against 1.d4 d5.
Tennison Gambit against the Scandinavian.
Grob Gambit against 1.g4 d5.
Avoidable depending on the opponents follow-up but easy to get:
Evans Gambit in the Italian.
Traxler against the Knight Attack (Italian).
Albin Countergambit against the Queen's Gambit.
Stafford in the Petrov.

Another important one is the Benko gambit if you're a d4 player.

there's also the infamous budapest gambit: 1.d4 nf6 2.c4 e5. Black's plans to attack the king side and if white isn't careful they could even be smother-mated! eg: 1. d4 Nf6 2. c4 e5 3. dxe5 Ng4 4. Nf3 Nc6 5. Bf4 Bb4+ 6. Nbd2 Qe7 7. a3 Ngxe5 8. axb4 Nd3#
