A little further afield, even higher temperatures have been recorded.
At 36 to 72 trillion degrees F, it would be hard to top the region around Quasar 3C 273, a region so hot that it stretches the limits of what was thought possible for plasma.

That converts to 20 to 40 trillion degrees Kelvin.

If we go really far back in history, we reach a moment right after the Big Bang. Scientists estimate a temperature of 1.8 octillion F (roughly 1 octillion K) when the Universe was just 10^(-32) seconds old.
