George Collison (1772–1847) was an English Congregationalist and educator associated with Hackney Academy or Hackney College, which became part of New College London—itself part of the University of London.

Collison was born in Beverley, Yorkshire, on 6 January 1772, and became articled to a solicitor in Bridlington. Taking a keen interest in the local Independent Chapel, he became an early Sunday school teacher, and in 1792 decided to give up law and train full-time as a minister at Hoxton College near London. In 1797 he settled close to London in the village of Walthamstow in Essex to carry out pastoral duties, becoming the minister of Marsh Street Congregational Chapel, in whose grounds he was buried in 1847. He undertook this ministerial role whilst also tutoring at Hoxton—until ill health led him to give up the latter in 1801. Detached from Hoxton, he was sought after by other educationalists, and was attracted to an offer to become the founding President and first tutor of a new theological institution, the Hackney Academy. This was to be based on the non-denominational principles George Collison was already familiar with, in his early associations with the London Missionary Society.

The Hackney Theological Seminary began in 1802 as a philanthropic non-denominational venture promoted by the Anglican Rev. John Eyre of Homerton, Secretary of the London Missionary Society and the Independent Rev. George Collison, with their associates. It started in Hackney village in 1803, gradually grew, moved across the city, and, long after Collison's death, it became part of the University of London.

On taking up the Presidency of the Hackney Academy in 1803, Collison continued some of his pastoral duties at Walthamstow, but was succeeded in similar work for a small congregation he had recently gathered in Hackney at the Well Street Chapel. Here, his successor, the Rev. Mr Hughes, inherited a rapidly growing interest locally in Independent worship, and his congregation grew so rapidly that little time passed before a larger Independent chapel (Trinity Chapel) had to be built in nearby Devonshire Road. Collison found a philanthropic use for his original chapel; it became the Well Street Chapel Free School, established in 1807 with generous endowments that covered the cost of educating sixty poor children and orphans who made use of the chapel itself for religious aspects of their attendance and had their school rooms and facilities at the back.

One of the Rev. George Collison's best known students was the philanthropist and founder of the London Orphan Asylum, the Rev. Dr Andrew Reed (1787–1862). Reed, who entered the college in 1807 and was ordained in 1811, became closely associated with Wycliffe Chapel in Shoreditch, where he remained pastor until 27 November 1861.

One of the Rev. George Collison's other students, Isaac Phillips, was involved in a trial at The Old Bailey. In 1822 he gave evidence against James Hamilton, a local painter and decorator who had returned to george Collisons house and college after carrying out refurbishments, to steal Isaac Phillips' purse containing fifty sovereigns. At that date such a considerable theft might have attracted a capital punishment, but the defendant appealed to the Rev. George Collison to save his life. He was found guilty of stealing and imprisoned for one year.

The Rev. George Collison had one daughter, Hannah; and a son, George Collison II. George II took up his father's previous occupation – law – and became Secretary and Registrar of the Abney Park Cemetery Company when it was founded in the late 1830s; he is considered to be the cemetery's founder. It was his initial research, including a visit to Massachusetts to observe the New World's non-denominational approach to cemetery design at Mount Auburn, and a study of London burial statistics designed to show a sufficiency of income from burials to maintain Abney Park as a historic parkland, that enabled his project to succeed. His close links to wealthy City Congregationalists, and to Congregational Ministers, also enabled him to form an unusually like-minded group of backers to launch and finance the venture.

All of the founders of the Abney Park Cemetery joint stock company were, like Collison, Congregationalists. The Congregationalists of London were already familiar with leading an avowedly non-denominational enterprise promoted largely by Congregationalists; their parallel in this regard being the London Missionary Society. George Collison II acted on behalf of the Abney Park Cemetery Joint Stock Company, to press home their 'New World' idea for a novel garden cemetery with a unique non-denominational design philosophy similar to the Congregationalists' approach to missionary work. George worked as the client representative to guide the company's architect William Hosking and its botanist and nurseryman George Loddiges, to bring about his desired effect.
