Simon F. "Sim" Walton (4 October 1880 – 27 December 1966) was an Irish hurler who played as a full-forward at senior level for the Kilkenny county team.

Born in Tullaroan, County Kilkenny, Walton first arrived on the inter-county scene at the age of twenty-two when made his senior debut in the delayed 1900 championship.

Walton was regarded as one of the top scorers of his generation and, in spite of an absence of records, it is believed he scored upwards of 30 goals.

Throughout his career Walton made 49 championship appearances, a Kilkenny record which stood until 24 July 1977 when it was surpassed by Eddie Keher.

Cork provided the opposition in the subsequent All-Ireland decider on 24 June 1906, the start of which was delayed by half an hour due to a heavy downpour.

Kilkenny played into the breeze for the opening thirty minutes, and a Dick Doyle gave the team an interval lead of 1–5 to 0–5.

Team captain Jer Doheny and goalkeeper Pat "Fox" Maher were singled out for particular praise as Kilkenny claimed a narrow 1–9 to 1–8 victory.

Kilkenny made it three provincial titles in-a-row in 1905, with Walton collecting a third Leinster medal following a 2–8 to 2–2 defeat of Dublin.

After a thrilling hour the game looked like ending in a draw, however, Jack Anthony cleared his lines and set up one final attack for Kilkenny.

The game was noted for its hard physical exchanges, however, a 4–6 to 0–12 victory saw Kilkenny defeat Tipperary for the very first time in championship hurling.

There was controversy in the subsequent All-Ireland series as Kilkenny were destined to play Limerick in the decider on 18 February 1912.

On the first occasion the pitch at the Cork Athletic Grounds was water-logged and the game was fixed for Thurles on 28 July 1912.

A substitute contest was played on 28 July 1912 when Tipperary faced Kilkenny after being nominated as provincial representatives by the Munster Council.

Walton was credited with scoring the winning goal, while he also had the honour of lifting the cup on behalf of his team.

After a low scoring 1–0 to 0-3 drawn game with Dublin in the provincial decider, Kilkenny secured a comprehensive 7–5 to 2–1 victory in the replay.
