The former Top Gear host, who has found renewed fame through his Amazon farming series, has been in a relationship with the 51-year-old Irish actress since 2016.
Fans of the couple were equally enthusiastic in their responses to the milestone announcement.
The pair have become familiar faces to viewers through Amazon's BAFTA-winning programme Clarkson's Farm, which documents life at the presenter's Cotswolds property.
Ms Hogan plays an active part in the day-to-day operations at Diddly Squat, helping to manage both the farm itself and its popular retail outlet.
Their relationship began in 2016, and the couple have since given audiences a candid look at their partnership through the farming documentary series.
The former actress has become an integral part of the show's appeal, with her interactions with Mr Clarkson providing both comedic and heartfelt moments throughout the programme's run.
Numerous followers took the opportunity to encourage the couple to take the next step, with one writing: "Put a ring on it. Women like this don't come along often!" whilst another urged: "Time to put a ring on the lovely Lisa!"
The question of marriage has been a recurring theme for the pair.

Ms Hogan revealed she attempted to propose during last year's leap day on February 29, when tradition permits women to ask the question.
However, she later joked that her efforts may have gone unnoticed. Speaking to The Times, she said: "Jeremy doesn't think I proposed, but he wasn't wearing his hearing aids, so no one will know."
In a Clarkson's Farm episode, when Ms Hogan asked if a promised surprise was a proposal, the Who Wants To Be A Millionaire host responded: "I'll think about the proposal, OK? I'm not ready yet."
The Amazon series has also captured moments of playful disagreement between the couple.

In one recent episode, Mr Clarkson flatly refused to join Ms Hogan for a wild swimming session, instead demanding she leave the water so they could visit the pub.
As his partner splashed about in a pond wearing a white swimming cap, the presenter grew increasingly impatient.
When Ms Hogan suggested cold water immersion offered an unparalleled natural high, Mr Clarkson countered: "I have been in cold water! I've done polar training - it was awful and trust me I've been drunk - and I've been in cold water - and being drunk is better."
Before meeting Ms Hogan, Mr Clarkson was married twice previously. He shares three children – Emily, Finlo and Katya – with his second wife Frances Caine.
