There are many legends linked to the temple and the annual seven-day stay of the central icons of Jagannath and his siblings during the Ratha Yatra.

A legend links the temple to Gundicha, the queen of Indradyumna (the legendary builder of the main temple) - after whom the Gundicha Temple is named.
Gundicha had a peep at the divine image of Jagannath being created by the celestial architect Vishwakarma.
Impressed by the image, she insisted on her husband building the temple for the deity and starting the Ratha Yatra.
Another variant suggests that Jagannath was pleased with her temple and promised to visit her house, now the Gundicha Temple.

As per another legend, when Jagannath (identified with the god Krishna) goes to stay for seven days in the Gundicha Temple, he intentionally leaves behind his consort Lakshmi locked up in a store room in the main Jagannath temple.
While in the Gundicha temple, he is exclusively taken care by his gopis (cow-herding girls) led by  his gopi-lover Radha like Krishna in Vrindavan.
The gopis are symbolized by the temple devadasis on this occasion.
 When Jagannatha returns to his main temple after his amorous dalliance, Lakshmi meets him at the main temple gate and sprinkles some magical powder on him, which makes him forget about his escapade in the Gundicha Temple, and she is immediately reunited with her husband in blissful love.

One more legend relates the temple's name Gundicha to a local goddess Gundicha, akin to Durga, worshipped to cure smallpox.
Gundi in Oriya means smallpox,  Gundicha is considered Krishna-Jagannath's aunt, which he visits with his siblings annually.

Another legend is about the mysterious disappearance of Chaitanya Mahaprabhu (an incarnation of Krishna according to the Bhavishya Purana).
He established Gaudiya Vaishnavism and also known to have composed the Jagannath Astakam.
He lived in Puri for many years and sang bhajans (devotional songs) and led sankirtan processions in front of Jagannath during his Chandan Yatra and Ratha Yatra, along with many devotees.
It is also said that Chaitanya Mahaprabhu used to go into a rapturous mood watching the god's love play and dance with joy and also fainted many times due to emotion.
Daily, he prayed to Jagannath, standing behind the garudastamba (Pillar of Garuda) with tears flowing down his eyes.
With permission of the king, Chaitanya Mahaprabhu once undertook the task of cleaning the Gundicha temple premises a day before the Ratha yatra (this tradition is followed even to this day by the followers of the Gaudiya Vaishnavism).
It is mentioned that once Chaitanya Mahaprabhu, unnoticed by his attendants, walked towards the Gundicha Temple and was last seen entering the Manikotha, thereafter he was never seen again.
This disappearance has remained an unexplained mystery as none of the books written on him have recorded this event.
It is believed that he merged with Jagannath at the temple.
