The first farm has been connected to high speed broadband under the National Broadband Plan.
The premises in Crossdoney in Cavan, owned by Tom Canning Agricultural Consultants Ltd, is now able to receive download speeds of 500Mbps.
"We are delighted to be the first farm business to be connected under the National Broadband Plan," said agricultural consultant, Tom Canning.
"The need for the farming community to be connected to a high-speed network is vital as administration and the day-to-day running of a farm has moved online."
"For the purpose of my farm consultancy business, I also need a reliable network connection so I can effectively operate business from a rural base and I am already seeing the benefits from this connection."
The connection is being provided via the retail partner, Eurona Arden Broadband.
A total of 544,000 premises across the country are due to be connected to high-speed broadband through the National Broadband Plan.
Each should be able to receive a minimum download speed of 500 Mbps when connected.
In January the first homes and businesses were connected to the fledgling network in Cork and Cavan.
"Today marks another major milestone in the rollout of the National Broadband Plan as we see one of the first farms connected," said Minister for the Environment, Climate and Communications, Eamon Ryan.
"Reliable access to high speed broadband will help farmers as they use agricultural technology to maximise efficiencies, diversify into more sustainable forms of farming, produce energy and run their day-to-day business operations."
