The Swindon Pride team say they were “touched” by the reaction they received for their event.
Organisers say more than 10,000 people joined the event at its new home in GWR Park on Saturday.
Sonia, The Cheeky Girls and The Royal Serenity were among the performers entertaining the crowd.
Andy Midwinter, from the Swindon and Wiltshire Pride team, said: “We are so touched by the reaction we have received, it was heartwarming to see our fans come with us to our new home and fall in love with the venue as much as we have.”
The After Party at Battle Boom Bar continued until the early hours, with a Beyoncé tribute act and DJ Nemz bringing the day-long festivities to a close.
Chairperson Paul Stewart added: “Volunteers are the lifeblood of Swindon and Wiltshire Pride. We are incredibly grateful to every volunteer for their valuable contribution.”
Mr Midwinter added: “Events of this size require a large group of people to make it happen, and as the organisers start to look ahead to next year, it’s clear that the demand will be as big as ever for it to return.”
