Getting a literary agent can be a stressful, difficult prospect and I hope this listing of reputable (as far as I know) agents who take romance will help you.  Please know that this listing is far from complete.  Many of the very best agents simply don't have websites, although many do seem to be catching up to the times.

This listing may be one starting place for you, but I will also suggest that you JOIN RWA!  They have a listing of agents who represent romance and keep tabs on their activity so you can be assured these people are on the up and up.  Not only that, but the RWR, the RWA monthly magazine, produces a list of all approved agents and their complete information each year. For a listing beyond those who have websites, another good resource is Karen Fox's website.  

I also hope you'll take a gander at my Agent F.A.Q., where I offer my personal take on agents in general.  Agencies are listing in Alphabetical Order by agency name or agent last name (if their site is not affiliated with their agency).

Be sure to check out the Writer Beware list of 20 WORST Agents, as well.

Alička Pistek Literary Agency, LLC -- Though this agency started in 2003, Alička Pistek was part of other agencies before. She represents commercial fiction (including romance). Check out her page of submission guidelines for more of what she personally likes to see as far as query letters.

Alive Communications, Inc. -- Representing many Christian authors, including Christian romance author Lori Copeland, this group may be an option for those of you writing to this specific sub-genre.  The website includes submission guidelines, a sample proposal, and industry links. Update: Alive Communications is now only open to submissions from unpublished writers referred by their current authors or published authors. 

Allen O'Shea Literary Agency -- Marilyn Allen and Coleen O'Shea are the agents here. Both once worked with major publishing houses and they do take romance clients. Submission guidelines are at the bottom.

Anderson Literary Management, LLC -- Kathleen Anderson, formerly of Anderson Grinberg and, before that, editor at Poseidon is the lead agent here. They do list lady lit and chick lit in their interests, though I don't recognize any romance/women's fiction names on their list. They're building a new website (the main link here), but still maintain a page at Publishers Marketplace here with all their info.

Artists Literary Group -- Represents romance/women's fiction and their new website has a lot more info on it than before, including author listing, info about the agents and submission guidelines.

Browne and Miller -- Formerly known as Multimedia Product Development, they have now officially changed their name. Danielle Egan-Miller is the AAR member who runs this agency (Ms. Browne passed away in 2003).  They are interested in romance. They do have submission guidelines, but also check out their section on how they work because I think it contains insights into the kind of relationship you might have if you're unpublished and can't sell right away.

Caren Johnson Literary Agency -- Caren Johnson formerly worked at Firebrand Agency and now runs her own agency. The site is part of her blog, but it does have the usual info and submissions guidelines.

Cornerstone Literary Agency -- Though the site is pretty barren, with only a short description of their submission guidelines, an address and a list of current titles, this agency is still well-known and respected.  Helen Breitwieser takes the romance.

I probably wouldn't submit here).

Martha Millard Literary Agency -- Another agent I'm not very sure of.  I've not heard of her before even though she says she has twenty years of experience.  She does accept romance (and says she's big with sci-fi/fantasy so paranormal writers may want to take a look).  Submission guidelines at the bottom of the page.
