Dr William Seller FRSE PRCPE (9 November 1797 – 11 April 1869) was a Scottish physician and botanist.
His father appears to have died when he was young and he moved to Bailie Fyfe's Close on the Royal Mile in Edinburgh with his mother.
In 1850 he was elected a Fellow of the Royal Society of Edinburgh, his proposer being Sir Robert Christison.
He won the Society's Makdougall Brisbane Prize for the period 1860-62 for his memoir of Robert Whytt.
The grave lies on the south side of the wall dividing the original cemetery from the northern extension, close to its eastern end.
