We're not talking about the hastily scrawled tags plastered along the sides of railway tracks and bridges, which give the art form such a bad name.
It's the colourful, inventive and often wittily subversive creations we want to celebrate - the kind of artwork which adds vibrancy to the capital's concrete nether regions and brightens up the days of those stumbling upon it.
The best graffiti, whether sprayed or brush painted, can hold its own with the grandest columns and sculptures decorating London's streets, and often has much more to say about the lives of those living amongst it.
Everyone gets themselves in a lather over the latest Banksy, with the Bristolian artist's darkly comic stencilled creations adding value to London's already astronomical property prices.
But there are plenty of other artists, many of them home-bred, producing equally eye-catching work across west London.
Below are a few examples of the area's best street art, but we'd love to hear your suggestions of masterpieces we've missed:
Big Mother, Charles Hocking House, Bollo Bridge Road, Acton
This 38m-high mural of a stick figure mother and child is reportedly the UK's tallest piece of street art.
It was created by Stik, an east London graffiti artist whose work causes almost as much of a buzz as Banksy's.
Visible from the Piccadilly line, it appeared on the side of a condemned block of council flats last November and was apparently painted to highlight the capital's affordable housing crisis.
Nature lovers may appreciate the less conspicuous but more life-like owl on the exterior of the building's ground-floor which, when viewed from the right angle, appears to be perched on the bollard in front of it. Thanks to @AtmStreetart for sharing this photo with us.
Feltham Circles, Pevensey Road Nature Reserve, Feltham
Amid the shrubbery and wildlife of this Feltham nature reserve are a collection of old circular sewage beds, which have been transformed into a striking graffiti gallery.
Nestled among the giant, intricately sprayed tags adorning these crumbling concrete monuments are a collection of colourful characters, from a horned ogre to a stoned hand grenade.
'Uxbridge Galleries', below the A40 between Denham and Uxbridge
Dubbed the Uxbridge Galleries by getwestlondon columnist Scott Balcony, this series of giant concrete 'canvases' takes some finding, but it's worth the effort.
Hidden beneath the roaring traffic of the A40, between Uxbridge and Denham, about 100 yards from the Grand Union Canal, is graffiti's answer to the Louvre - a vast array of bizarre and wonderful designs covering the concrete slabs holding up the flyover.
One of the more eye-catching walls has been reimagined as the home of a nattily dressed hound, complete with a pun-tastic framed picture reading 'bone sweet bone'.
If you do fancy checking it out, Scott's instructions are to walk from the Swan and Bottle pub in Oxford Road along the canal towards Denham, veering right along a footpath lined with brambles and stinging nettles when you reach a small old brick bridge.
Smile, wall of Platform 3 bar in Whitton Road, Hounslow
She was quickly restored to something approaching her former glory by a mystery admirer, but her brief wardrobe change did help clear one thing up.
The graffiti had been assumed by many fans to be the handiwork of Banksy, as it bears many of his hallmarks.
But graffiti blogger @artofthestate pointed out it was actually by Propapropaganda, who is the creator of an almost identical piece in the Leake Street tunnel below Waterloo.
Towpath mural beside Grand Union Canal, Brentford
The giant water rat staring out from this canal-side wall might cause some passersby to jump, but he's part of a generally rather cheery mural created by young offenders.
Teenagers from Hounslow Youth Offending Service teamed up with the Canal & River Trust and Positive Arts to create the 100m-long artwork close to Brentford Dock.
Inspired by the work of Vincent Van Gogh, who lived in nearby Isleworth for three years, the swirling motifs frame images of the architecture and wildlife found along the canal.
It was actually painted to cover up less appealing graffiti which had for years blighted the wall of the historic warehouse.
Miley Cyrus wrecking ball, Hammersmith
The singer, who controversially bared all for the video, is shown reducing the fairy tale Walt Disney castle to rubble as the cartoon mouse looks on disapprovingly.
The artwork, attributed by some admirers to Banksy, appeared last year on a wall close to the Eventim Apollo, where the artist had performed in 2008 as her former alter-ego, the wholesome Disney character Hannah Montana.
Community mural in Wornington Green, North Kensington
This very recent addition to west London's street art scene has the approval of one of James Bond's right-hand men.
It was designed by Fiona Hawthorne, whose husband Colin Salmon appeared in three 007 films as a high-ranking MI6 aide alongside Pierce Brosnan.
She said the mural - on a ramp in Wornington Green, North Kensington, close to where the couple first met - was inspired by "the rich tapestry that makes this community".
Barnet of graffiti tags in Ladbroke Grove
Thanks to Clare Docherty for pointing out these eye-catching graffiti murals in Ladbroke Grove, which we missed from our original list.
At first glance, the top image looks like a straightforward portrait but look a little closer and you'll see her luxuriant black hair is actually made up of dozens of enmeshed graffiti tags. Very clever.
Anyone inspired by the images above should of course bear in mind that graffiti is illegal unless you first get permission from the owner of the property in question!
