20 Best 40th Birthday Gifts for Your Boyfriend

This is our top pick for a 40th because it addresses something every man starts to notice around now: tight shoulders, a stiff lower back, calves that complain after a run. The Mini is small enough to keep on the couch or in a gym bag, so he will actually use it, and it is a quality piece of kit most men would never buy for themselves.

If he scrolls his phone in bed and wakes up to a blaring alarm, the Restore offers a gentler routine: wind-down sounds at night and a slow sunrise in the morning. Better sleep is an underrated gift at 40, and this one also keeps the phone off the nightstand.

Most men wear the same worn-out slippers for a decade. The Ascot is the grown-up replacement: wool-lined suede with a real rubber sole for a dash to the mailbox. Check his shoe size before ordering, since they fit true to size.

If his wallet, keys, watch and phone end up scattered across the dresser every night, this wooden dock gives each one a place and charges the phone while he sleeps. A grown-up upgrade from a pile of chargers.

If his wallet is a stretched-out bifold full of old receipts, the Slim Sleeve is a clear upgrade. It holds the cards he uses every day, slides easily into a front pocket, and the leather ages well, which feels fitting for a 40th.

For the boyfriend who fixes things, camps or just likes having the right tool on hand, the Wave Plus is the one most people keep for life. Pliers, blades, screwdrivers and a saw fold into a pocket-sized tool with a 25-year warranty.

If he regularly asks where his keys are, a four-pack of AirTags is a practical gift that saves both of you time. Put one on his keys, his wallet, his gym bag and his suitcase. It only works with an iPhone, so check before buying.

A smoker kit turns an old fashioned into a little show: the torch lights a pinch of wood chips, the cloche traps the smoke and the drink comes out tasting like a cocktail bar. Six chip flavors give him plenty to experiment with at his 40th and long after.

An etched globe decanter on a wooden stand with two glasses makes a good-looking centerpiece for his bar cart or office shelf. It is a classic milestone gift for a man who likes to pour a drink for guests.

For the boyfriend who mans the grill, this is the gift that takes the guesswork out of steak and brisket. The wireless probe stays in the meat while he relaxes with guests, and his phone tells him exactly when to pull it. It is a great price for a gift he will use every weekend all summer.

If he has moved from mixers to sipping bourbon or Scotch neat, a set of Glencairns is the glass he deserves. The shape concentrates the aroma, and four glasses means he can share a bottle with friends. Pair them with a bottle of his favorite bourbon or Scotch for a complete gift.

Fill thirty scratch-off coupons with things only you can give him: a lazy Saturday, his favorite dinner, a weekend away, a round of golf without complaint. It costs under $10 and pairs well with a bigger present.

Load the Aura with photos from your relationship, his childhood and his friends before you give it, then invite his family to add more. It is a sentimental gift that keeps updating, which suits a milestone birthday better than a single framed print.

Forty is often when people get curious about where their family came from. An AncestryDNA kit gives him an origins map, traits and possible relatives, and it makes for a great conversation over dinner when the results arrive.

Back to the Future came out the year before he was born, and it is still one of the most-loved films of a 1986 kid's childhood. This small LEGO DeLorean is a quick, fun build and looks great on a desk. A cheap, clever add-on.

An 18-ounce gold-trimmed beer glass printed Vintage 1986 is a fun first pour on the night of his 40th, and a cheerful reminder every time he cracks a cold one afterward.

A small crochet potato holding a sign about his back and body hurting is the kind of gag gift that gets passed around the room. It is the perfect cheap laugh to tuck in beside his real present.

A 1986 cap is a crowd-pleaser at a 40th party and a decent everyday hat after it. Hand it over at the start of the celebration so he wears it in the photos.

A 20-ounce insulated tumbler with a Back in 1986 design keeps coffee hot on the commute or a drink cold on the deck. It is a playful birthday nod that he will still use in March.

This oversized card doubles as a guest book: leave it on the table at his party and let friends write messages. He ends up with a keepsake full of handwriting from everyone who came.
