Question: Is condensed milk the same as sweetened condensed milk? 

I have a fudge recipe that calls for condensed milk and I can not find strictly condensed milk, only sweetened condensed milk or evaporated milk.

Answer: 
In my experience, "condensed" milk refers to the sweetened product, and "evaporated" milk refers to the unsweetened product. People will often say "sweetened condensed" for clarity, but this is not strictly necessary: if your recipe calls for condensed milk, use the syrupy stuff.

However, if this is an older recipe, all bets are off: older casual usage had "condensed" for both meanings. (Hence using the "sweetened condensed" phrasing, even though it's a bit of a tautology.)
As a recipe developer / chef... 'Sweetened Condensed Milk' and 'Condensed Milk' are exactly the same product - just labeled differently by different manufacturers for different markets. Condensed milk is ALWAYS sweetened.

Here's the lowdown:

Evaporated Milk, is just that. Milk that has been evaporated with 60% of the water removed. This product has NO sugar added.

'Sweetened Condensed Milk' and 'Condensed Milk' take this evaporation process a step further and add up to 40% sugar by volume. 

So to sum up:

* 'Sweetened Condensed Milk' and 'Condensed Milk' are exactly the same product.
* 'Sweetened Condensed Milk' and 'Condensed Milk' are both up to 40% sugar by volume.
* Evaporated milk contains no added sugar.

Really hard to believe that the other answers here are so wrong...
