The "Happiest Homecoming on Earth" was an eighteen-month-long celebration (held through 2005 and 2006) of the fiftieth anniversary of Disneyland Park, also celebrating Disneyland's milestone throughout Disney parks worldwide. In 2004, the park underwent major renovations in preparation, restoring many attractions, notably Space Mountain, Jungle Cruise, the Haunted Mansion, Pirates of the Caribbean, and Walt Disney's Enchanted Tiki Room. Attractions that had been in the park on opening day had one ride vehicle painted gold, and the park was decorated with fifty Golden Mickey Ears. The celebration started on May 5, 2005, and ended on September 30, 2006, and was followed by the "Year of a Million Dreams" celebration, lasting twenty-seven months and ending on December 31, 2008.

It was expected to stay closed until at least December 31, 2020. In February 2021, Disneyland announced a limited-capacity ticketed event called “A Touch of Disney”, which would offer guests to shop at stores and enjoy eateries around the park from March 18 through April 19, 2021.
