Taghmaconnell also known as Taughmaconnell (Irish: Teach Mhic Conaill, meaning 'MacConaill's house'), is a small village in County Roscommon, Ireland. It is situated between Athlone and Ballinasloe. The village lends its name to the parish and civil parish in which it is located.

The local economy is predominantly based on agriculture, with many residents being farmers. Additionally, some villagers work in large factories and government offices in the nearby towns. The village has one of the lowest crime rates in the country.

Athlone is 14 km (9 mi) to the east, and Ballinasloe 10 km (6 mi) to the south-west. There are castle ruins to be seen in Castlesampson, Clonbigney and Dundonnell.

The local church in Taghmaconnell is dedicated to Saint Ronan, who also had connections with the Aran Islands and Clonmacnoise. The important focal points within the parish include Saint Ronan’s Well, the National School, and the Church, all depicted on the parish banner. The current Parish Priest is Fr. Sean Neylon. The present church dates back to 1805, before this the church was built it seems that mass was celebrated in a big barn across the road in what used to be Costello's shop. The first building on the present site was erected in 1805 on land donated by Brabazon Newcomen.

In 1860 a new church was built out of the foundations of the 1805 one. In 1961 major work was done on the church. The mortuary was built and the front door was set in. Wooden statues that were found under the altar during this renovation certainly came from Clontuskert Priory. They are now in the Diocesan Museum beside the Cathedral in Loughrea. All date back to 1200 to 1300 AD.

St Ronan’s well is situated in the townland of Shraduff in Taughmaconnell. Mass is celebrated at the well annually on 21 June, the summer solstice. According to local tradition, Saint Ronan, on his way from Aran to Clonmacnoise, stopped at the spring well for a drink. A woman with a blind child was present at the well. Saint Ronan blessed the well and anointed the child’s eye with its water, miraculously restoring the child's sight.
