Queensborough is an unincorporated community in the municipality of Tweed, Hastings County, in Central Ontario, Canada.

Queensborough was part of the incorporated (today geographic) Elzevir Township[3] before the creation of the amalgamated municipality of Tweed on January 1, 1998.

[5] The first European to settle the area was Miles Riggs in 1830 who built a sawmill then later a flour mill.

[4][5] The flour mill was purchased in 1850 by Daniel Thompson, who renamed the settlement so as to be permitted to open a post office.

The community is a canoe and kayak destination for paddlers descending the Black River in spring as part of the M.A.C.K.fest (Marmora Area Canoe and Kayak Festival),[4][7] and has been recognized by Whitewater Ontario "…in appreciation of the Queensborough Community's ongoing hospitality to whitewater paddlers…".
