    What to Write in a Niece's Engagement Card

    There are plenty of ways to relay your best wishes for your niece's engagement or niece's wedding wishes, but there are a few traditional talking points you may want to include when drafting your note. There are, of course, also many different approaches you can take for your engagement card that depend on your relationship with your niece, whether you go sentimental, brief and sweet, humor-filled or a combination of all three. Regardless of the vibe you're going for (and maybe you're not even sure yet), we have you covered with some prompts to congratulate your niece on her engagement in your card, letter or email.

    • Share how happy you are that she found her person.
    • Tell her you want to take her and her partner out to celebrate.
    • Tell her how proud you are of her.
    • Shout out how much you love her fiancé with an example or two of your favorite characteristics.
    • Express your excitement and enthusiasm for the wedding.
    • Offer your support with wedding planning, advice or anything she may need on this journey.
    • Recount a favorite memory you share with her or her and her partner.

    Short Engagement Wishes for a Niece

    If you prefer to avoid an extra-lengthy or sentimental tone in your niece's engagement card, make sure your words pack a punch. Going the simple route makes sense for several different reasons, especially if you aren't super close with your niece or if you haven't met (or don't know much about) her fiancé yet. As much of a cliché as it may be, it really is the thought that counts. As long as you speak from the heart, it'll still be a touching gesture they'll appreciate.

    • Congrats! We couldn't be happier to celebrate your upcoming wedding!
    • We're so excited to celebrate with you at your engagement party! Until then, sending virtual hugs.
    • To my sweet niece, I'm happy you've found your person. Congrats!
    • Niece, I'm thrilled to celebrate your engagement. Here's to a great couple!
    • Congratulations to my favorite niece!
    • You're getting married! I'm thrilled for you.
    • Can't wait to see you walk down the aisle!
    • Congratulations, niece, on your engagement.

    Funny Engagement Wishes for a Niece

    While you don't want to go overboard with jokes and roasts, infusing some humor into your engagement wishes to your niece can be a great choice. Of course, we don't suggest going the funny route if you don't know them super well or haven't seen them in years—unless they're known for their jokes, pranks, etc. In that case, amping up the comedy is totally fair game, within reason. Either way, we always recommend avoiding jokes targeted at their new fiancé unless you know them very well—offending someone in a congratulatory engagement card is never a good look!

    • I never thought we'd see the day when you settled down, but after getting to know [fiancé's name], we certainly understand the pivot!
    • Congrats! We couldn't be more thrilled you found someone to put up with your nerdiness. Kidding. We love you.
    • They finally put a ring on it—and that's a big reason to celebrate! In all seriousness, we're so happy to expand the family and celebrate your upcoming wedding.
    • We knew you were full of it when you said you weren't the marrying type, but we get it—you chose a total gem!
    • You're engaged! We can't believe you found someone to put up with your cooking…just kidding! Please don't stop bringing that sweet potato casserole to Thanksgiving dinner.
    • I was going to write a funny congratulations message but thought I should save all my good jokes for the wedding toast.
    • Congrats, niece! Time to start practicing saying "I do"...and "I told you so!"

    Sentimental Engagement Wishes for a Niece

    Whether they've been dating their partner for over a decade or just a year or so, finding your forever person is a huge moment in your niece's life. If you feel like it deserves some extra-thoughtful messages, consider including some sentimental touches in your niece's engagement wishes. Opting for a softhearted tone of voice doesn't mean you have to go full-on dewy-eyed (though you certainly can, if you feel your niece would be receptive to it), but you can pack a punch with a few key phrases, personal memories or characteristics. Go sappy or sweet—either way, if your niece appreciates sentimentality in general, it's a great way to express your excitement for the upcoming wedding.

    • To my lovely niece, you deserve all the happiness the world has to offer, and this engagement is just the beginning of your happily ever after. Congrats!
    • Congratulations! You will make the best wife. I couldn't be more excited you've found your life partner in this crazy world. Sending all my love to the happy couple!
    • Wow, I couldn't be more excited that you and [fiancé's name] are headed to the altar. I've never met a couple more obviously in love and compatible. I can't wait to help you plan the big day!
    • Congrats to the most beautiful bride-to-be. Marriage is one of the best gifts in life, and you will make the most wonderful wife. I am honored to be a part of your union and so excited to celebrate the two of you!
    • "When you realize you want to spend the rest of your life with somebody, you want the rest of your life to start right now." (When Harry Met Sally)
    • Niece, I am just so happy that you found the love of your life—and that our family will gain a new member. Cheers to the most lovely bride-to-be!
    • I'm getting emotional just writing this card—I can only imagine the waterworks when I see you walk down the aisle. Congratulations, my beautiful niece.
    • Sending many beautiful engagement blessings your way, my beloved niece. I hope you have the loveliest wedding and happiest marriage.
