In tokamak reactors, approx 300 million degC
The temperature required for nuclear fusion to occur is around 100 million degrees Celsius.
It is called the enthalpy of fusion of a substance, also known as (latent) heat of fusion.
Heat of fusion is called the latent heat of fusion because it is the heat energy required to change a substance from a solid to a liquid phase, or vice versa, without a change in temperature. This heat energy is "hidden" as it is being used to break the intermolecular bonds holding the substance together, rather than increasing its temperature.
The heat of fusion is the amount of energy required to change 1 unit mass of a solid to a liquid at constant temperature.
"Cold fusion" refers to fusion at (or near) room temperature, rather than the millions of degrees that are normally required. This has not been achieved so far - at least, not to any significant degree.
The temperature required for nuclear fusion to occur is around 100 million degrees Celsius.

It is the amount of energy required to change 1kg of solid into a liquid with no temperature change.
The temperature of nuclear fusion is typically around 15 million degrees Celsius. This extreme temperature is required to overcome the electrostatic repulsion between positively charged atomic nuclei and allow them to fuse together to release energy.
At the center, both the temperature and the pressure are highest. Both a high pressure and a high temperature increase the likelihood of fusion.
It is called the enthalpy of fusion of a substance, also known as (latent) heat of fusion.
How can temperature either help fusion to occur or prevent fusion from occurring?
Wipeout Fusion happened in 2002.
Metroid Fusion happened in 2002.
Dark Fusion happened in 1988.
