A golf marking flag for attachment to a supporting upright pole having flag attachment means comprising a linear sleeve adapted to loosely slip over the upright pole to enable unobstructed rotation of the flag in response to wind direction along with a flexible tab secured to the top of the linear sleeve and adapted to rotatably engage an upwardly extending narrow pin located at the top of the upright pole. The flexible tab contains an opening larger than the narrowed upright extension to enable free rotation of the tab around the narrowed extension, while the opening is smaller than the upright pole to enable the larger pole to vertically support the marking flag. The flexible tab supports the marking flag on the upright pole while the sleeve enables rotation of the marking flag about the upright pole. The golf marking flag can be attached directly to an upright pole or adapted to be interconnected to an intervening swivel harness to provide indirect connection to the upright pole. A golf marking flag with direct and indirect connections to the upright pole provides a universal golf marking flag attachable to all types of upright poles and avoids manufacturing and stocking multiple marking flags dependant upon the style of intervening swivel connectors for interconnecting flags to poles.
