The 57-year-old singer brought the youngster - who had celebrated her big day earlier in the week - out on stage at the latest show in her 'Rebel Heart' tour and asked the crowd at the American Airlines Arena in Miami to join her in serenading her daughter.
After the musical tribute, Madonna then presented Mercy with a candle-topped cupcake.
She later shared a picture of the moment on Instagram, alongside the caption: "Make a Wish Mercy James."
Earlier in the week, the 'Living For Love' singer - who also has children Lourdes, 19, Rocco, 15, and David, 10 - had used her Instagram account to wish Mercy a happy birthday.
Alongside a smiling picture of herself and the birthday girl, she wrote: "Happy Birthday to my Beautiful Mercy James! (sic)"
Madonna has also used her social media page to thank fans for their support as she prepares to do battle with ex-husband Guy Ritchie over custody of Rocco, who is currently in London with his filmmaker dad and refusing to return to New York.
Captioning a sweet letter from her supporters, she wrote: "Thanks soooooo much for this! It means a lot to me! One word of kindness it can save me! (sic)"
The message, signed from 'Your Rebel Hearts', pays tribute to their idol for "rescuing [them] every single day".
One part read: ""We're crying with you, but we know you will get through this as you always do. You were born as a lion, and lived as a lion. We just want you to know that our love for you rescues us every single day, and we hope ours could do the same."
