Two guests flagged down a passing motorist when the Florida kingsnake was spotted in the grounds of St Bridget's Roman Catholic Church in Baillieston on Saturday, June 14.
The driver stopped to help before contacting Scotland's animal welfare charity.
The three foot long snake is now in the care of the charity's Lanarkshire Animal Rescue and Rehoming Centre in Hamilton, where he has been nicknamed Vince after one of the stars of the film Wedding Crashers.
Animal Rescue Officer Jan Toraman said, "Apparently Vince caused quite a stir at the wedding and gave the guests a real fright.
"When I arrived Vince had slithered into a nearby garden and he wasn't very happy to be rescued.
"We think there may be someone in the area missing their snake and they'll no doubt be surprised when they hear what he's been up to.
"Anyone who recognises Vince should give us a call on 03000 999 999.
"If no one comes forward for him we'll find him a new home."
