So far, there are three Lion King films. I only know of The Lion King, The Lion King II: Simba's Pride, and The Lion King 1½. The order in which you can watch them chronologically is The Lion King, The Lion King 1½, and The Lion King II: Simba's Pride.
The Lion King, Lion King 2 Simba's Pride, Lion King 1 1/2
Three. The Lion King, The Lion King 2: Simba's Pride and The Lion King 1½: Hakuna Matata which is semi-officially called "The Lion King 3" (as in, in European DVD releases' covers.) There are lots of rumours that there's gonna be "The Lion King 4" but there is no official source for that - besides it would likely be The Lion King 3 if there ever was going to be a fourth movie because as said the third made is most officially 1½ and not 3.
