Visitors from across local business toured the 30 exhibition stands and took advantage of networking opportunities over lunch.
Both the 60 Minute Seminars, which focused on improving marketing and sales techniques delivered by Chamber members, were also full.
Chamber chief executive Paul Griffiths said: “Our vision is to build and nurture a respected, influential business community, and share knowledge, advice and opportunities and our Business Exhibition has a vital role in making that happen.”
The exhibition took place at Novotel Milton Keynes. The Chamber’s aim was to encourage businesses to forge new contacts, share expert knowledge and showcase the wealth of products and services available in Milton Keynes.
Mr Griffiths said: “There was a fantastic buzz throughout the whole day and the response from businesses and visitors has been phenomenal.
"It was also very encouraging to see businesses using social media, and in particular, the #ChamberMKexpo hashtag to engage with us so positively on twitter.”
