Canon
Being from tow different Disney movies, Elsa and Rapunzel never met in canon. However, the two are implied to live in the same universe, as Rapunzel made a cameo along with Eugene in Frozen, entering to see Elsa's coronation. They also met in Ralph Breaks the Internet, where they and the other Disney Princessess are fellow netizens in Oh My Disney. There are also some Disney crossover games where the two can be in the same team, depending on the payers choice.

Both Elsa are Rapunzel where born with magical powers. While Rapunzel has blonde hair because of the Sundrop Flower powers, it is kinda possible that Elsa also had white hair because of her ice powers. Because of ther powers, the two have lived single and under control most of their lifes. Rapunzel was kinapped and locked in a tower, while her presumptuous mother told her that the outside is dangerous, only in order to use her hai to keep herself young. Meanwhile, Elsa was sepearated by her sister by their parent, and lived with afraid of her powers most of her life, while their parents told her to conceal it, thought unlike Gothel, Agnarr and Iduna wanted the best for Elsa. Between the beginning and the middle of the movie, the two take the courage of disobey what they parents have told them all their lives, with Rapunzel coming out the tower and Elsa exploding her powers, and finally fell free.

Both Elsa and Rappunzel have a very beloved person, Anna and Eugene respectively, who almost sacrifice their lifes for them nearly the end of their films. When it seemed that there was not solution, because Rapunzel had lost her powers and Elsa didn't known how to defrost, they miraculously managed to revive Anna and Eugenne and the end. After all, the two finally could live normal lifes in their kingdoms.

Fanon
Both Elsa and Rapunzel are major members of the Rise of the Tangled Frozen Dragons crossover. The ship can also been considered par of the Disney Princesses fandom as well. The ship sailed due their similarities, as well as their contrasts in personalities and powers. Fanworks often show the cold/warm contrast between them, as well as their symbols being a snowflawe and a sun respectively. Some people believe that Rapunzel's blubby personality would remind Elsa of Anna.

There is a popular theory telling that Rapunzel may be Anna and Elsa's cousin, after her cameo in Frozen I. Some people even have theorized that Elsa may be Rapunzel's biological sister and not Anna's. Other people simply like protaying them as friends. The infamous shipping wars between Jelsa and Jackunzel have made some people rival Elsa and Rapunzel, what inspired some people to making them friends or shipping them in order to stop these wars.

The paring have also been seen in some AUs. The Frozen Tangeld Guardians AU has Rapunzel as Elsa and Anna's mother, and Jack Frost as their father. Modern AUs usually have them wearing their Ralph Breaks the Internet otfits. In some Wicked Aus, Rapunzel and Elsa are choiced as Glinda and Elphaba respectively, when Anna doesn't take that place.

In AO3, the ship has 40+ work, while Fanfiction.net has 112 works of them together and only 3 under the pairing tag. There's a good amount of fanarts and fanvids of them as well
