The council commemorated Merchant Navy Day by raising the Red Ensign flag at its headquarters in Giffnock.
East Renfrewshire Council annually recognises the contribution of the seafarers who embody the Merchant Navy.
In the ceremony, Provost Mary Montague and Philip Rodney, deputy lieutenant of Renfrewshire, paid tribute to veteran merchant seafarers and those who are currently serving.
The event welcomed local dignitaries, elected members, and members of the community to acknowledge the UK's reliance on merchant seafarers.
Provost Montague said: "Merchant Navy Day is an important date in the Council's calendar each year and is our annual opportunity to honour merchant seafarers for their service and sacrifice.
"It marks the date when the first British merchant ship SS Athenia was sunk by a German torpedo in the Second World War with the loss of more than 120 passengers and crew.
"During the First and Second World Wars the brave men and women worked tirelessly to keep our nation afloat and supply lines open.
"Today the Merchant Navy enables approximately 95% of the UK's trade which moves by sea, whilst they continue to face the dangers of the high seas.
"Without these officers our shops, pharmacies, and supermarkets would face empty shelves."
Mr Rodney said: "Today, provides an opportunity to celebrate and honour the invisible service and the many courageous men and women who serve or served in the Merchant Navy.
"Their bravery provides us with the opportunity to remember how they kept supply lines open during two World Wars and more recently during the Covid pandemic.
"Their contribution must never be forgotten."
