The England midfielder slammed a first-time strike home towards the end of a first half in which Stoke had chances to take the lead, before Terry met a Lampard corner with his head to make it two in the second half.
The best of the Potters' chances came, typically enough, from a Rory Delap long throw on 15 minutes.
The early pressure brought by Stoke, and evidenced mainly by trademark Delap set-pieces, waned as the Blues began to put their foot on the ball with more intelligence.
Prior to the goal striker Didier Drogba chested down and volleyed mightily towards the far corner, only for Whitehead to get enough of a head on it to send it just wide.
And from the resulting corner the ball dropped to Terry on the far side of the box. He took his time to tee up the arriving Lampard at the edge of the box - the ferocious strike took a slight deflection off Abdoulaye Faye and flew past Thomas Sorensen.
Right-back Branislav Ivanovic mimicked the Delap tactic for Chelsea, with little success. There was more promise in the feet of Anelka as he sought ways through the resolute Stoke backline.
The France striker should have scored a second goal when Drogba worked some space on the right side of the area and crossed expertly to the far side, where Anelka's header was tipped around the post.
Alex went close from Florent Malouda's resultant set-piece, but Stoke could not prevent a goal from the second one.
Lampard this time took the kick and planted it straight on to the head of Terry, whose near-post effort came off the rising shoulder of a flailing Andy Wilkinson.
A dipping Lampard strike was scrambled wide by Sorensen before both Anelka and Kalou wasted chances to make it 3-0 when through on goal, Lampard the provider.
Ricardo Fuller had led from the front for Stoke, chasing and harrying, but saw a late shot after turning Alex inside-out tipped wide by Hilario.
Villa it is for Chelsea in the last four at Wembley in a repeat of the 2000 FA Cup final, the last to be played at the old stadium.
