The Queen is due to visit Scotland's largest city as part of her week long trip north of the border to celebrate her Diamond Jubilee.
She will start the day with a thanksgiving service at Glasgow Cathedral, where she will be accompanied by the Duke of Edinburgh, before paying a visit to George Square in the city centre.
The royal couple will then visit St Margaret's Hospice, in nearby Clydebank, and afterwards attend a lunch in the grounds of Our Holy Redeemer Primary School in the town.
The Hospice has provided care to patients with advanced life-limiting illnesses and older people with complex medical and nursing needs for almost 60 years.
It offers a range of facilities to the local and wider community including a day care centre, out-patient facilities, home care and counselling services.
The royal party will then proceed further west to Greenock to officially open Inverclyde Council's new £2 million customer service centre at Greenock Municipal Buildings.
The events mark the third day of the Queen's visit to Scotland, which began with an engagement at Edinburgh's newly-refurbished Scottish National Portrait Gallery on Monday.
The Queen's annual garden party in the grounds of Holyrood Palace took place on Tuesday, with 8,000 guests attending from across Scotland.
Earlier in the day, the Queen presided over an investiture ceremony which saw around 70 people receive honours.
Other events include a service at St Giles' Cathedral in Edinburgh on Thursday at which the Duke of Cambridge will be installed as a Knight of the Thistle. On Friday, the Queen and Duke of Edinburgh visit Perth, which was awarded city status to mark the jubilee.
