Katherine Agnes Watson (1918-2008) was a poet and bookseller, publishing The Source and Other Poems in 1956.

After serving in the Women's Royal Naval Service, 1941-1946, Watson joined the Roman Catholic Church and in April 1949 became a postulant at Holy Cross Abbey, Stapehill, Dorset. Later that year, she returned to secular life, and in 1950 undertook a pilgrimage to Rome from Austria by bicycle, which she describes in Pedallers to Rome. The theme that runs throughout her writing is her sense of conflict between her strong religious convictions and her poetry. An equally important influence was her companion Pamela Redmayne, with whom she lived from 1964 until Redmayne's death in 1991.

In 1952, Watson was in a relationship with the literary critic and scholar John Bayley (1925-2015) who during this time proposed marriage. This did not materialise and Bayley later married Iris Murdoch (1919-1999) in 1956. Their correspondence shows that by 1994 Watson, Bayley and Murdoch were in regular amicable contact.

From 1959-1969 Watson edited 'Nemo's Almanac', an annual literary competition. In 1966 she realised her ambition to own a bookshop, opening Watson's Bookshop in Burford, Oxfordshire, which she ran until it closed in 1980. She died in 2008.

Watson's account of her pilgrimage, Pedallers to Rome was published posthumously by her friend and literary executor Carolyn M. King in 2012, along with her Collected Poems (2012).
