The 1992–93 Regal Trophy was a British rugby league knockout tournament. It was the 22nd season that the competition was held, and was the fourth staging of the competition since it was re-named the Regal Trophy.

Wigan defeated Bradford Northern by the score of 15-8 in the final to claim the trophy. The match was played at Elland Road, Leeds in front of an attendance of 13,221.

This season saw several changes in the entrants, one club re-formed/renamed, two French clubs were invited instead of the junior clubs, and one club withdrew. This resulted in one less club/entrant reducing the total number to thirty-seven.

The changes, in detail, are:

1. Trafford Borough re-formed as Blackpool Gladiators and moved back to Blackpool, playing at Jepson Way, Blackpool
2. Two French clubs, Carcassonne and XIII Catalan were invited to join the competition, instead of the junior clubs, who were no longer invited
3. Scarborough Pirates went into administration at the end of previous season

The preliminary round involved ten clubs, to reduce the numbers of entrants to the first round proper to thirty-two.
