Ironically you need to look under laws against Holocaust Denial to find anything useful about it on Wikipedia as far as I can tell, as that page includes references to laws that more generally disallows denial of genocides and crimes against humanity:
France and Germany, for example, has laws that while containing bits and pieces that are specific to nazism, also targets genocide and crimes against humanity in general.
Switzerland and Portugal are examples of countries with laws that don't explicitly mention Holocaust denial but where many forms of Holocaust denial is covered by laws placing restrictions on denial of genocide in general.
I was wrong about France actually. It appears that the wording in the French law is narrower than it first appears.
It is a bit confusing as it looks wider until you consider the condition "such as they are defined by Article 6 of the statute of the international tribunal military annexed in the agreement of London of August 8, 1945". That tribunal explicitly was only able to rule on acts carried out by Axis countries, so this law only applies to those acts specifically.
Look up the laws of the countries that I referenced. They have laws that either outlaw denying any genocide, or laws outlawing the denial of the nazi and communist genocides and mass atrocities.
Also, "I've looked it up real quick but I can't see" is hardly the way to approach this if you think you have even the slightest point.

Or are you talking about something else?
