40th Birthday Wishes

53 wishes · updated October 14, 2026

Forty is one of the big ones. It's the age where people often take stock: of family, career, health, friendships and what they still want to do. Some turn 40 with a big party and a trip; others want a quiet dinner and no fuss about the number. Either way, a thoughtful 40th birthday message helps them feel celebrated rather than reminded of the clock.

On this page you'll find 40th birthday wishes for a friend or best friend, your wife or husband, family members, coworkers and your boss, plus funny "over the hill" lines (kept kind), inspirational messages and short texts.

After the list, there's a guide to choosing the right tone for 40, writing a personal card, and giving a toast at a 40th birthday party.

  7. Happy 40th birthday. I've been trying to think of how to sum up what you mean to me, and I keep coming back to the little things: the soup you brought over when I was sick, the way you remember my kids' names and birthdays, the long walks where we solved the world's problems and then forgot the answers by dinner. Forty years have made you wise, steady and still completely yourself. I hope this decade gives back to you a little of everything you give to the people around you. You've earned it many times over.

The right tone for a 40th birthday

Forty jokes are everywhere, from "over the hill" decorations to reading-glasses gags. They can be a lot of fun, but they work best when the birthday person clearly enjoys them. A few guidelines:

  • Funny is fine when the jokes are about shared experiences: naps, knees, early bedtimes, not knowing new slang.
  • Skip the sensitive stuff: weight, wrinkles, gray hair for someone who minds it, or anything about "running out of time" for kids, marriage or career goals.
  • Balance the joke with a sincere line. One laugh plus one real sentence about what they mean to you is the perfect 40th card.

If the person is going through something hard, such as a divorce, health issues or a job loss, choose a warm, encouraging message over humor about age.

What to write in a 40th birthday card

  1. Celebrate who they are now. Name a quality that's grown stronger with age: patience, humor, confidence, generosity.
  2. Mention something they've built. A family, a career, a friendship, a community, a garden.
  3. Look forward. Wish them something for their forties: adventure, rest, a dream they've talked about for years.

Worked examples

For a friend: "Happy 40th, Dana! In the twenty years I've known you, you've raised two great kids, started a business and never once missed my birthday. I hope your forties bring that trip to Italy you've been planning forever. Love you."

For a husband: "Happy 40th, Mike. You're the most patient dad and the best partner I could have asked for. I can't wait for the next forty years of road trips and backyard dinners together."

For a coworker: "Happy 40th, Raj! Your calm in a crisis is legendary around here. Hope your birthday is relaxing and your new decade is full of great things."

Surprise parties: a few tips

Forty is a popular age for a surprise party, but not everyone enjoys being surprised. If you're planning one, check quietly with their partner or closest friend first. Keep the guest list to people they'd actually want in the room, plan around their work and family schedule, and have a backup plan in case they make other arrangements. A card from every guest, collected at the door, gives them something to read the next morning when the noise has died down.

Giving a 40th birthday toast

Forty is a classic birthday for a speech at dinner or a party. Keep it to about two minutes:

  1. Start with who you are. "I'm Lisa, and I've had the privilege of being Tom's sister for thirty-seven years."
  2. Tell a story. One anecdote that shows their personality. Gentle teasing is fine; avoid anything that would embarrass them in front of their kids or colleagues.
  3. Say what you admire. One or two sentences about who they've become.
  4. Toast the next chapter. "To Tom, to forty, and to the best decade yet."

Ideas to make a 40th memorable

  • Forty notes. Collect forty short messages from friends and family, one for each year.
  • A decade-by-decade slideshow. Photos from each decade make a great backdrop at the party.
  • A shared experience. A weekend away, a concert, a cooking class or a long-planned trip.
  • A time capsule. Have guests write a note for the birthday person to open at 50.

When they don't want a fuss

Some people would rather let 40 pass quietly. Respect that. A heartfelt card, a small dinner with close family, or a sincere text can mean more than a surprise party they didn't ask for. You can still mark the milestone in a personal way without making the number the center of attention.
