Freezing point of pure water alone is zero degree centigrade. As soon as the temperature starts dropping below zero water begins to freeze.
If you add chemicals to water like salt or ethylene glycol etc. you are lowering its freezing point. You can only lower freezing point of water by so much - otherwise by increasing concentrations of other chemicals it would no longer be water.

Even in the antarctic the portion of water that is far removed from the surface ( that is deep insde the ocean, that keeps the icbergs afloat and moving ) and is mobile does not freeze.

Therefore if the water is insulated enough it would not freeze in the worst conditions of temperature.

Water by itself will always freeze, at least on Earth anyway. Even moving water freezes. Haven't you seen a picture of a frozen waterfall? There are some chemicals that can be added to water ( I think the one I'm thinking of has something do with with Calcium ) that can make its freezing point much much lower, but I'm pretty sure it will always always freeze.

Your question sounds like a rhetorical one, which is ok and valid enough but, answered rhetorically, has probably more answers than you likely expected. "There are many ways to keep water from freezing", even forever!, as some of ur answer's have pointed out. However, I liked your question just the way it is because it's so captivating. It really deserves a fascinating answer. Hopefully the kind I'm about to give..... the best I could muster.
So,......... here's my answer:

(droplets that have been trapped in bubbles within fossil amber underground).

In your question, you used the word "never"
That word implies having to contain the water in question.
One of the strengths of my answer.
Water is hard to isolate forever and must be thought of as part of a larger system. Water is highly mobile and moves all around the planet changing phases as it meets different temperatures. Even water frozen at the arctic poles will sublimate into gas and be transported back to southern regions to re-enter the water cycle. Given enough time, water travels / moves through almost all substances including rock. If it can get into a substance, it can also usually get out. Even water in a hardened lava bubble is not trapped. It will move through that substance in molecular form to once again become part of the water cycle on our planet. Single molecules of water can be bonded to other particals for considerable time but, this becomes a very loose definition of "water". Unless physically trapped , (which is very difficult to do), most water must be considered as part of a larger system,"The water cycle".
(on this or any other planet)

Here's the exception: 20 million years ago, raindrops were indeed "trapped" in the exposed sap of certain species of trees. Buried deep underground in a tropical country that is now the Dominican Republic, miners have discovered samples of fossilized amber containing bubbles of fossilized air and water.
While holding and tilting the sample, you can watch the water moving within these tiny air bubbles. Fossil amber even has the ability to preserve delicate biological structures such as DNA for 100 million yrs and was the source of impetus for the movie Jurassic Park.. Amber is not composed of mineral like other fossils. Amber is still an organic substance and also carries an electric charge. ( which is probably part of the reason why it can hold onto the trapped water for 20 million years and counting).
'Never' is a harsh word but, as long as the planet stays intact and other samples of such amber remain buried and undiscovered, those droplets of water should never freeze.

There may even be more examples in nature, of trapped water in locations that always remain above freezing but, this is the only example I can think of.

Ofcourse,.. speaking rhetorically, there are many ways you can always keep water from freezing just by applying some external force.... eg, if you apply heat the water won't freeze, etc. right?........ However, literaly speaking,
it's kinda hard to apply such an external force forever?

( just trying to offer something unique yet definitive and remain within the literal parameters of ur question)

All water will freeze, I have seen parts of the water falls frozen and some small ones completely frozen. The rivers, even very large rivers freezes over, in places, Once in a blue moon all north American lakes have frozen over.

The Arctic and the Antarctic both are salt water oceans and they stay frozen all the time at least some part of it.

Everything freezes.

water under enough pressure to lower the freezing point to lower than the temperature of the water.

raising pressure on ice will cause it to ,melt even while keeping it below the freezing point of water.

so if you continuously increase pressure in the right increments to comensate, you could, theoretically, keep lowering the temperature, and it will never freeze.

what water will never freeze?
answer: water under constantly increasing pressure.

From a scientific standpoint, there is not enough data to answer this.
But here goes anyway:
1) Constantly heated water
2) A picture of water
3) Superheated water or steam
4) Water that's already frozen
See my point? Revise the question or add more constraints and ask again.

I feel stupid I always thought it was salt water that didn't freeze

water freezing depends on the temperature and what is in it.
