Best Man Speech Opening Lines

Opening lines by tone.

The examples below are starting points. Use the line that fits your personality, then replace generic wording with the groom's name and one detail the room will recognize.

Funny but safe opening: "Good evening everyone. I am the best man, which means I was trusted with a microphone, a timeline, and several stories I have been specifically asked not to tell."
Heartfelt opening: "For those I have not met yet, I am the best man, and I am lucky enough to know the groom as both a friend and one of the most loyal people in my life."
Brother opening: "I am the groom's brother, so I have known him through every version of himself, including a few versions we are all grateful did not make it into adulthood."
Short opening: "I will keep this brief: I love these two, I am proud to stand here, and I have one story that explains why."
Formal opening: "Good evening. On behalf of the wedding party, thank you for being here to celebrate a couple who mean so much to all of us."

How to choose your first sentence.

A strong opening does three jobs: it says who you are, creates the right level of energy, and points toward the story. If you are nervous, choose a short line. If you are naturally funny, choose a joke that makes the groom more likable, not smaller.

Use "For those I have not met" if many guests do not know you.
Use a brother line if your sibling relationship is central.
Use a formal line if the room is traditional or mixed-age.
Use a funny line only if you can deliver it calmly.

Opening lines to avoid.

Some openers make the room tense before the speech has even started. Avoid anything about exes, drinking, private embarrassment, family conflict, or jokes that depend on guests already knowing the story.

A safer test is simple: would the groom, the partner, parents, and grandparents all still feel respected after the first sentence? If the answer is not clear, soften it.

Turn the opening into a complete speech.

After the opening, move into one groom story, explain what it says about him, mention the partner, and end with a direct toast. You can use the best man speech template for structure, browse best man speech examples.
