An alcohol‑free zone could be trialled at Cardiff's Principality Stadium following complaints about the behaviour of drunk fans.
Welsh Rugby Union chief executive Martyn Phillips said it could be in place in time for next year's Autumn internationals.
It comes after some people reported bad behaviour at the latest matches.
Phillips said a survey found the "stadium experience ranks above other experiences people have in sport".
The WRU asked 2,500 people what they enjoy and what they do not enjoy on a match day.
Phillips said alcohol was a "hot topic" and they "now understand that it is a big part of the experience" for lots of people.
