Sister of the Groom Speech: How to Write a Great One

Giving a sister of the groom speech is a highlight of any wedding.

This is an opportunity to praise your brother, share childhood memories, and welcome the bride as a new sister into the family.

Whether you’re the younger sister or the groom’s sister writing about your older brother, this will help you write a speech that’s funny, engaging, and personal.

Opening Your Speech: Grabbing Everyone’s Attention

The opening sets the tone for your sister of the groom speech and helps you connect with the audience. Here’s how:

Be Grateful

Start by thanking everyone at the wedding reception, including other family members who have come to join in the fun. For example:

• “It’s great to be here today and share this with all of you on this crazy day. Thanks for coming to [Groom] and [Bride]’s party.”

Introduce Yourself

Mention your connection to the groom:

• “For those who don’t know me, I’m [Your Name], the younger sister of [Groom], who is an awesome brother and now an even more awesome man.”

Start with Humour or a Sweet Story

Humor is a great opener. Share a funny or embarrassing story:

• “Growing up [Groom] was my go-to person for advice and trouble. He was my cookie thief at midnight and my bike-riding teacher. He’s always been the best older brother anyone could ask for. But let’s not forget the time he thought he could pull off a mullet – it was a brave but questionable choice!”

Your Bond: Praise Your Brother

This part of your sister of the groom speech template is about your relationship and who he is as a person.

His Character

Talk about his qualities:

• “From day one, [Groom] has been my protector, my fan, and my best mate. He’s not just my older brother; he’s also my friend and someone I’ve always looked up to.”

A Sweet Story

A nice story adds depth to your sister of the groom speech. Think of a time he helped you out or made you laugh:

• “In college, I had a tough time. [Groom] would call me every night to check-in. That’s the kind of awesome man he is – always putting others first.”

Childhood Memories: A Personal Touch

Adding childhood memories is a great way to make your sister of the groom speech personal and sentimental.

Choose a Relatable Story

Pick a memory that shows his personality:

• “As kids [Groom] loved building forts and going on wild adventures. That’s the same creativity and determination that will make him an amazing partner to his new wife.”

Connect the Memory to Now

Show how those traits apply to today:

• “That sense of adventure led him to [Bride], his biggest adventure yet. I know he’ll approach married life with the same passion and heart.”

Welcome the Bride: New Sister

Your perfect sister of the groom speech should also welcome your new sister-in-law and celebrate her relationship with your brother.

Praise the Bride

Say something nice about her:

Their Love Story

Say what makes them a great match:

• “[Groom] and [Bride] together is like two best friends who are in perfect sync. Whether they’re making pancakes or planning their next adventure, their love is beautiful.”

Welcome

Welcome your new sister-in-law:

• “To [Bride], I’m so happy to officially call you my new sister. We’re lucky to have you and I look forward to many more memories.”

Funny Groom Moments

Share some lighthearted moments or embarrassing stories about the groom:

• “As the groom’s sister I’ve seen him in all his glory—and his not-so-glory moments, like when he tried to cook spaghetti for the first time and ended up with something that could only be described as soup!”

Groom Speech Jokes

Use some light marriage jokes to balance it out:

• “Marriage is about compromise. For example [Bride] will learn to love [Groom]’s love of football and [Groom] will learn to enjoy Hallmark movies. Right [Bride]?”

Advice: Sharing Your Wisdom

If you’re married or have learned from happy couples, now’s the time to share your advice.

• “Marriage isn’t about being perfect; it’s about finding someone who makes life’s imperfections worth it. [Groom] and [Bride] you’ve already proven you’re perfect for each other.”
