Praseodymium(III) fluoride is an inorganic compound with the formula PrF3, being the most stable fluoride of praseodymium.


The reaction between praseodymium(III) nitrate and sodium fluoride will produce praseodymium(III) fluoride as a green crystalline solid:[3]

Pr(NO3)3 + 3 NaF → 3 NaNO3 + PrF3
