White Christmas, anyone? It’s a hit with our family.
Raising Arizona, a little offbeat for a romcom
High Fidelity
Maid in Manhatten
Dan in Real Life
Monster in Law
Something’s Gotta Give
The Bodyguard
As Good as It Gets
Runaway Bride
Two Week’s Notice, another Hugh Grant movie.
Loved A Little Romance!
More recent, but I like how Bridesmaid’s played out. Love that Irish? guy!
Chris O’Dowd played the lovable Irish cop in Bridesmaids.
Another Irish actor… Domhall Gleeson in the rom/com jewel… About Time
Roxanne
Serendipity
@beerme I saw him in an episode of Doc Martin! He’s a great actor. I’ll have to look up About Time :).
“You’ve got Mail” is free with prime right now on Amazon
I also like “The Decoy Bride” with David Tennant
“Groundhog Day”!
Also, “Made of Honor”
I don’t know if it qualifies as a rom-com, but I don’t know what else it might qualify as, and it’s fundamentally the most romantic movie I know: Before Sunrise.
I really love Four Weddings and a Funeral. The rest of the Hugh Grants I can sort of take or leave; I’m most likely to take Notting Hill.
The Philadelphia Story. Unmatched, ever. And It Takes A Thief.
Lady and the Tramp, of course. And Beauty and the Beast.
Also, teen rom-coms: Pretty In Pink, Some Kind of Wonderful, Clueless, 10 Things I Hate About You. I love all of those. And the Lindsay Lohan remake of The Parent Trap, a rom-com with teens.
Love Actually is probably my favorite, but I also love Music and Lyrics.
I also love The Proposal even though I generally find Ryan Reynolds objectionable.
You forgot Sixteen Candles 
^ The Matt Dillon doppelganger actor was so cute!
If we’re including teen rom-coms, I also like The Duff. And Easy A.
I like Sixteen Candles most of all, probably, but I have a hard time thinking of it as a romantic comedy since the object of Molly Ringwald’s affection has four or five lines in the whole movie, only a couple of which are directed towards her. The rom is all in Ringwald’s head, which is fine and age-appropriate, and the big payoff is not a mutual acknowledgement of love, but a realization that yes, she is cute and boys are going to like her.
Another movie I think is a great teen rom-com: American Pie.
How to Lose a Guy in 10 Days.
A little com, but mostly rom, About Time and Once. Must see movies!!
I was initially going to list this one as a joke. :))
Juno
As Good As It Gets, Silver Linings Playbook, Lars and the Real Girl, The Sound of Music, My Fair Lady.
@JHS, True that the characters didn’t have a real relationship, but it does have a sweet ending. As all good rom-coms should.
I think a lot of even the more mature romantic movies, whether comedies or not, have characters that are sort of admiring each other from afar, wondering if their attraction is mutual, etc.
@psychmomma I loved Once. Not a rom-com, but a great movie.
If we’re throwing out roms, not coms, I liked Somewhere in Time also. And of course Out of Africa, which BTW shared part of the musical soundtrack with Somewhere in Time. The composer was John Barry and just listening to the music makes me cry.
Nine Months (great cast-Hugh Grant, Julianne Moore, Tom Arnold, Jeff Goldblum, Joan Cusack)
